what the compounds do to living organisms.

• Working with your partner, look the descriptions over &

identify the medicinal use card that best fits the description.

Why do you think plants produce such a wide variety of

poisonous compounds?

• Plants use these as defenses against things that might

eat them. The compounds might be distasteful to

herbivores, & may even make them sick!

How can it be possible that modern medicine uses poisons as

medicine?

• Poisons & medicines are the same thing. The difference

is dosage & how the compound is used. A very small

amount of poison can help cure many conditions.

AngiospermsAngiosperms vs. Gymnosperms.

Angiosperms:

• Derived from Greek meaning “container”.

• Plant which bears seeds in fruits or mature ovaries.

• Form flowers that carry reproductive organs & fruits.

• Most diverse of the plant types.

AngiospermsAngiosperms vs. Gymnosperms.

Gymnosperms:

• Seeds are not included in fruits.

• Plants that bear seeds directly on sporophylls or naked

seeds without coverings.

• Very few species due to the lack of seed protection.

• Naked & unprotected seeds need to get into the ground

quickly to take root or risk damage by animals or weather

conditions.

AngiospermsAngiosperms vs. Gymnosperms

Angiosperm Gymnosperm

Seed Production:

Seed is produced by flowering

plants & are enclosed within

ovaries or fruits

Seed is produced by non-

flowering plants & are

unenclosed or naked

Lifecycle:

The lifecycle of these plants

are seasonal (annuals,

biennials, & perennials)

These plants are evergreen

Leaf Structure: Leaves are broad, flat shapeLeaves are scale-like &

needle-like in shape

Distribution: Relies primarily on animalsRelies primarily on the wind &

water

gymnosperm plant?

AngiospermsAngiosperms vs. Gymnosperms

AngiospermsStrawberries?

• The ripe, red, fleshy part that we think of as the strawberry

“fruit” is actually swollen receptacle tissue.

• Sometimes strawberries are called "aggregate accessory

fruits" since the part we eat comes from the part that holds the

ovaries instead of the ovaries themselves.

• The “seeds" you see on the outside of a strawberry are

actually the plant's ovaries & are called "achenes.“

• Each “seed" is technically a separate fruit that has a seed

inside of it.

AngiospermsComparing monocot & dicot.

• There are many exceptions to the characteristics in both

groups.

• No single characteristic in the list will infallibly identify a

flowering plant as a monocot or dicot.


Monocots Dicots

Embryo: Single cotyledon Two cotyledon

Pollen: Single furrow or pore Three furrows or pores

Flower Parts: Multiples of three Multiples of four or five

Major Leaf Veins: Parallel Reticulated

Stem Vascular Bundles: Scattered In a ring

Roots: Adventitious Develop from radicle


• Basis for distinguishing the two classes.

• Cotyledons are the “seed leaves” produced by

the embryo.

• Absorbs nutrients packaged in the seed until

first true leaves produced for photosynthesis.

Monocots Dicots

Embryo: Single cotyledon Two cotyledon


• The first angiosperms had pollen with single

furrow or pore, retained in many monocots.

• Most dicots descended from a plant which

developed three furrows or pores.

• Counting the petals, stamens, or other floral

parts can be helpful.

• Not always reliable in some flowers with

reduced or numerous parts.

Monocots Dicots



• Parallel veins run the length of the leaf.

• Reticulated usually contain numerous auxiliary

veins which “reticulate” (resembling a net or

network) between the major ones.

• Not always reliable in some leaves.

Monocots Dicots



• Vascular tissue occurs in long strands called

vascular bundles.

• Conductive tissue through which water &

nutrients are transported.

Monocots Dicots



• The radicle is part of a plant embryo that

develops into the primary root.

• In monocots the radicle aborts & new roots

arise adventitiously (without organization).

• “No School”

AngiospermsGrab a ChromeBook from the cart.

• Be sure to grab the number that corresponds to the number

on your desk.

• Once you log into the google classroom you will have an

assignment titled “Plant Angiosperm Formative Assessment

#1”

• Complete the assignment on your own. Does not require any

discussion, there are only eight questions.

AngiospermsSeeds.

• They are enclosed in the ovaries protected from the

environment & predators.

• Seeds contain the embryo, endosperm (stored food), &

testa (seed coat).

• The testa may also be winged or variously ornamented with

prickles or sclerified (protective tissue with thickened walls)

hairs.

AngiospermsSeed Dispersal.

• Plants spread their seeds in many ways:

- Blown by the wind.

- Fall into water & carried to new locations.

- Carried by insects, birds, or mammals.

AngiospermsSeed Dispersal by Wind.

• Seeds are modified:

- extremely small & light

- winged

- plumed

- covered with woolly hairs

- surrounded by explosive capsules

that forcefully eject seeds into the air.

AngiospermsSeed Dispersal.

• Plants spread their seeds in many ways.

- Blown by the wind.

- Fall into water & carried to new locations.

- Carried by insects, birds, or mammals.

AngiospermsSeed Dispersal by Water.

• Fruits & seeds adapted to float on water.

• Adaptations include aerenchyma (soft tissue containing air

spaces) in fruits or seeds & light weight.

Coconut Seeds

AngiospermsSeed Dispersal by Animal.

• Generally occurs by two methods:

- Ingesting (internal), then excreting them.

- Passive transport (external)


• Ingestion

- Diet often consists of fruits & seeds, therefore

designed to be eaten & dispersed.

- In many cases, full or partial digestion is

required for seed germination.

- In the Amazon, many fruits & seeds are eaten

& dispersed by fish during high tides.

Blackberries

Blueberries


• Passive Transport

- Seeds contain modifications that enable them to attach to

the external body parts of animals.

- Burrs, barbs or other structures get tangled in an animals

fur or feathers.

AngiospermsSeed Dispersal Methods.

AngiospermsSeed Growth.

• For a seed to germinate (start growing) it needs enough

moisture & the right temperature.

• Ideal conditions can be different for different plants & even

different offspring from a single plant.

• Moisture causes the testa to split so the radicle (root tip) can

grow into the ground or cotyledon (seed leaves) can emerge.

AngiospermsSeed Growth.

• Seeds use the endosperm (stored food) to grow until

production of photosynthetic leaves.

• Developing seedling respond to light (phototropism) &

gravity (gravitropism)

(6:31):

Assignment: In a paragraph (4-5 sentences) summarize the

reason for storing so many seeds & what else are the stored

seeds used for?


(6:31):

Synopsis: In this brief talk from TED U 2009, Jonathan Drori

encourages us to save biodiversity - one seed at a time.

Reminding us that plants support human life, he shares the

vision of the Millennium Seed Bank, which has stored over 3

billion seeds to date from dwindling yet essential plant species.
