HOW ANIMALS REPRODUCE?

&nimals produce animals like themselves5 this process is called reproduction. &nimals

reproduce se'ually.

,n se'ual reproduction5 a sperm from the father unites with an egg from the mother in a processcalled fertilization. he fertilized egg develops into a new individual. he fertilized egg is called a

zygote. he zygote that develops into a new individual or !a!y animal.

here are two ways !y which the eggs and sperms of animals are !rought together.


3/13

releases her eggs into the water at the same time that a male releases his sperm. -ome sperms come in

contact with some of the eggs and fertilization takes place.he entire process during which eggs and sperm are released into the water and the eggs are

fertilized is called -7&>,>?. &lmost !ony fish reproduce this way.

,n time5 the eggs @1A hatched. hen the eyes are formed first.@2A hen the head emerges fromthe egg. @3A he !ody and tail also grow out from the egg and the last part of the !ody that develops is

the !elly @A ,t !ecomes smaller5 and the fish appears like a normal fish.=oist fish have a spawning season each)year. hey can spawn several l time. -ome !reedthroughout the year.


4/13

season5 the !utterflies also emit chemical scents called 74R


5/13

LIFE CYCLE OF A FRUIT FLY

& fly starts from an egg. hese eggs are long and white. he housefly lays 1++ to 1#+ eggs at a

time in decaying matter. he eggs5 which are a!out one millimetre long5 hatch within 12 to 2 hours.

hen they hatch5 the eggs turn into larvae. hese larvae are known as maggots. hey feed on decayingfood and gar!age. &fter few days5 the larva$s kin turns into cocoon and !ecome a pupa. he pupa is in

a tough shell. ,t will develop into an adult fly in 3 to " days. lies move around. hey walk5 settle andfeed on human and animal wastes and other decaying matter. hey suck the fluids of decaying matter5which have germs. hese germs can cause diseases like cholera diarrhea5 diphtheria5 scarlet fever5

dysentery and gastro interitis. hey may carry also viruses of polio and other serious diseases. he

germs of viruses will stick to the hairs of their antennae and their legs will !e transferred to uncovered

food on your dinning ta!le.

THE LIFE CYCLE OF COCKROACH

he life cycle of cockroach starts from an egg. he mother cockroach lay these eggs in dark5

dirty places such as ca!inets5 storerooms5 kitchens5 and other places where gar!age is kept. hese eggs

are !rown in color and are attached to the walls5 papers5 !ooks5 and even in clothes. hen the eggs arehatched5 a !a!y cockroach comes out. his is called a nymph. &fter several days5 the nymph !ecomes

an adult cockroach. ockroaches are enemies of man. hey carry germs which they take from gar!age

can and other dirty places.. hen they crawl on our food it !ecomes contaminated with germs. he

cockroach also gives off !ad odor that is also left on the food it crawls on.

Uses o A!"#$%s &o &'e (o##)!"&*

&nimals have !een very useful to people since the !eginning. &nimals !ecome sources of food and

clothing. hey also serve as companions and helpers of people. =ost of the foods we eat come from

animals. =ost of the animal proteins the ilipino eat come from seafood$s such as fish5 shrimps cra!s5and shellfish. =eat such as !eef5 pork and poultry come from animals that are raised to !e slaughtered

and eaten !y people. oney5 eggs5 and milk come from living animals. 0ees give us honey. hicken5

ducks5 6uails5 and turkeys give us eggs. =other cows5 cara!aos5 sheep5 and goats give us milk. =anycows are raised to produce chicken eggs5 6uail eggs5 duck eggs.

CLOTHING

7eople get clothing materials like wool. 9eather5 or silk from animals.. ool comes from

sheep. 9eather comes from skin of animals. -ilk comes from fi!ers made !y silkworms.

ur is the thick growth of hair that covers the skin of animals. oats and other articles ofclothing may !e made from fur. ur coats are very e'pensive and are valued for the !eauty and the

warmth that they provide. 9eather comes from !oth the warm)!looded and cold ) !looded animals.

9eather is used to make shoes5 gloves5 hand!ags5 8ackets5 pants5 skirts5 and suits . 9eather used forclothing is usually made from cowhide.

WORK

-ome domesticated animals help people work. ara!aos pull plows in rice fields. orses and

camels carry people from one place to another.

orking dogs vary greatly in size and in the purposes. -ome working dogs are used forguarding. he !igger ones are used for hauling loads or for rescue work. or e'ample5 -i!erian huskies

pull sleds.

ANIMALS AS PETS

7ets are interesting5 playful companions. 7eople en8oy teaching them to do tricks and to o!eycommands. &side from providing companionship5 many pets also serve other useful purposes. Dogs

hunt5 guard properly5 herd cattle and sheep5 and assist !lind people. ats often keep homes and !arns

free from mice and rats. 7ets such as frogs and toads help keep gardens free from certain kinds of

insects.

COMMON PETS

SUMMARY

&nimals reproduce animals like themselves !y se'ual reproduction. Reproduction is7ossi!le when fertilization occurs.

ertilization is the union of the father$s sperms and the mother$s eggs. 4'ternal fertilizationoccurs when eggs are fertilized outside the mother$s !ody. ,nternal fertilization takes place when theeggs are fertilized inside the mother$s !ody.

-ome animals are !orn alive. -ome are !orn as eggs.

4ggs are hatched or incu!ated to develop as !a!y animals.

-ome animals look like their parents !ut are smaller in size. &s they grow5 they grow more hairor feathers and increase in size. -ome grow other !ody parts like horns and long tusks.

ish lay their eggs in water. he process !y which the fish eggs are released in water and are

fertilized is called spawning.-ome animals undergo metamorphosis. =etamorphosis means change in appearance and form.

=etamorphosis may !e complete or incomplete.

,ncomplete metamorphosis is one that undergoes only three stages of development egg5 larva 5and adult. ,t lacks the pupal stage. 4'amples are grasshoppers and dragonflies.

omplete metamorphosis is one in which the animal undergoes four stages of development.

4gg5 larva5 pupa5 and adult. 4'amples are !utterflies and mos6uitoes.

&nimal$s pets provide companionship5 assist in hunting and herding5 assist !lind persons5 serveas guards and help children learn responsi!ility. ommon pets are dogs5 cats5 !irds and fish.

he kind of pet to own de3pends on where you live and how !ig your place is. aring for pets

re6uires proper housing5 enough e'ercise5 a !alanced diet and medical treatment if necessary.4ven as animals undergo changes as they develop maturity5 people also change to !ecome fit

and more useful citizens.

0e kind to animals5 wether they are raised as pets or for food production. reat them kindly andproperly. hey should !e given their needs in order to keep them healthy and so that they live longer.

&nimals like people5 have !asic needs food5 shelter5 e'ercise5 and medical treatment. hese

should !e provided5 especially for animals that are food sources in order to produce !etter foodproducts that will !e healthful for the consumers.

4ven as animal$s needs are provided5 children have their !asic needs and rights5 which the

adults should attend to.

&nimals are !asic part of our environment. 9et us try to conserve them. &void endangeringanimal lives and eggs. 7revent animal e'tinction. elp in the preservation of all forms of animal life.

& machine called an incu!ator is used for the incu!ation of !irds$ eggs with newly hatched

chicks5 and even human !eings. ,ncu!ators maintain the proper temperature and proper humidityfavoura!le to good development.

&nimals must !e handled properly while !eing transported5 wether to change residence or for

selling.

FLOWERS

P$+&s o &'e F%o,e+s

&ll flowers have petals and sepals !ut they vary in shapes and colors.

7etals are the most attractive part. hey give the flowers their shapes and colors. 7etals make up

the corolla.&t the !ase of the petals are the sepals. hey are green leaflike structures that hold the petals

together. hen these sepals are put together5 they make the caly'.

&t the center of the petals is the pistil. he pistil is the female reproductive organ of the flower.

here are three parts found in it. hese are the stigma. -tyle5 ovary. he stigma which is sticky is theflat top of the pistil. he style is the stalk which holds the stigma. &t the !ottom is the ovary. ,nside the

ovary are the ovules. he ovules are the female cells of the flower.&round the pistil are the stamens. he stamen is the male reproductive organ of the flower. ,t

has three parts the filaments5 the anther5 and the pollens. he filaments is made up of a slender stalk. ,t

!ear or holds the anther. he anther or pollen sac produces and releases the pollen or male se'ual cells.

omplete flowers have sepals5 petals5 stamen5 and pistil which differ in num!er5 shape and sizefrom one flower to another.


7/13

4ach flower has its own specific num!er of petals and sepals. -ome flowers have three petals

and sepals while others have five. here are some flowers that are so small that they are not usuallyseen as flowers.

Ho, F%o,e+s Dee%o "!&o +)"&s

&fter pollination5 the fertilized ovules !ecome seeds.0efore an ovule !ecomes a seed5 the pollen produced !y the anther must reach the top of thestigma. hen it goes down to the ovary where the ovule is.

he transfer of pollen grains from anther to stigma is called pollination. hen this happens5

fertilization occurs. ,n some cases5 the pollen grains from the anther of a flower simply falls on the

stigma of the same flower or another flower of the same plant. his kind of pollination is called self)pollination. ross pollination is the transfer of pollen grains from a flower of a plant to the flower of

another plant.

learly5 most pollen grains travel5 they ride on the wind5 water of !odies of insects. -ome arecarried !y !irds and even man.

,nsets such as !ees5 !utterflies5 !ettles5 moths and flies carry pollen grains as they go from

flower to flower to get food in the form of nectar. he fragrance structure5 and color of many flowershelp to attract insects

& !ird can also carry pollen grains on its feet and !ill. hen it steps on a flower and transfers to

another flower5 it can pollinate.

7eople pollinate flowers through cross)!reeding in the la!oratory to have !etter flowers. henthe wind !lows5 light and tiny pollen grains of a flower are transferred to other flowers.

hen it rains5 pollen grains of flowers growing high lands can !e transferred to the flowers in

the lowlands. &6uatic plants can also !e pollinated !y the pollen grains carried !y the water.

P$+&s o &'e See/

he seed is matures ovule. ,t contains a partially developed plant called an em!ryo. he em!ryois usually made up of the hypocotyl5 ridicule5 plumule and cotyledons. he hypocotyl is the part

!etween the cotyledons it develops into the stems of the plant. he radical is the lower part where the

root grows. he plumule is the growing lea at the tip of the hypocotyls of a seed. he cotyledonprovides food for the growing em!ryo.

& flowering plant with two seed leaves is called a dicotyledon or dicot for short. & dicot plat

usually has neeted)veined leaves. ,ts flower parts are in ets of four or fives. ,t has a layer of cells

!etween the wood and the !ark.lowering plants with an em!ryo containing only one cotyledon are called monocotyledons or

monocots for short. & monocot usually has parallel)veined leaves. ,ts flower parts are in sets of threes.

,t has no secondary growth in its stems and roots.

7eople are agents of seed dispersal5 farmers scatter corn seeds5 mongo and other seeds for more

production of these plants.

-eeds that travel !y land are called hitchhikers. hese seeds have prickles that easily stick tothe fur or feet of !irds and other animals. hen the animals step on the mud5 the seeds will !e

implanted in it.0irds pick fruits for food. hey eat only the soft part of the fruits then scatter these fruits withseeds to the ground. &fter several days5 some of these seeds will sprout.

-eeds that are soft and fine are also dispersed !y the wind. Dandelion seeds are among them.

-uch seeds are often called flyaways. =ost of the seeds that travel !y water are light enough to float.

he seeds scattered in highlands are carried down to the lowlands. hen it rains. um!leweeds have auni6ue way of scattering their seeds. he whole plant dries up and rolls along the ground5 dropping its

seeds as it turns over and over.

Ho, P%$!&s Re+o/)(e Ase1)$%%*

7lants are all around us. ey grow not only from the union of the male and female seeds5 as in

pollination !ut also from other parts of the plant. Reproduction without the union of the male andfemale germ cells is called ase'ual.

here are several plant parts which may !e used in ase'ual reproduction such as:

1. 0ul! F a !ul! is an underground !ud or swelling that sends down roots. ,t consist of a very short

stem with leafy layers as in an onion.

2. u!er F a tu!er is a short5 thickened5 fleshy part of an underground stem of a plant like the

potato. he new plant developed from the !uds or eyes that grow in the tangles of the tiny

leaves of the tu!er.

3. Runner F a long slender horizontal trailing stem tht puts out roots along or 8ust !elow the

ground at its tip of nodes5 producing new plants. &n e'ample of a plant that grows from stemsis the straw!erry plant.

. utting F a growth5 sprout or twig cut away from a plant for rooting or grafting. 4'amples are

ornamental plants lke santan5 roses5 sampaguita5 san rancisco and !ougainvillea. amote and

cassava are plants that grow from cuttings too.

7lants reproduces ase'ually through:

1. 0uding F occurs when a !a!y plany develops from the !ody of the mother plant. hen itmatures5 it !reaks off and !ecomes and independent plant.

2. ission F happens when the paent plant divides into two individual plants.

3. ?rafting F grafting is the process of inseing a !ud @scionA of one plant into the stem or trunk

@stockA of another. ,t continues to grow and !ecomes a permanent part of the plant.

. =arcotting @marcottageA F a process of !inding a root to medium to a hard stem to produce

another independent plant.

". 9ayering F the process of !ending down a shoot or twig then partly covering it with soil so that

roots can grow.

#. loning F cloning is the latest techni6ue of producing a duplicate of a plant !y replacing the

seed of an unfertilized egg with the seed of a !ody cell from the plant.
