TRANSCRIPT
PLANTPRODU
CTION
Parts of the PLAN
TS
ROOT
A part of a plant that takes water and mineral for the plant.
STEM
Transport sap and water throughout the plant.
LEAF
Part of plant where food is made by photosynthesis.
Section of a LEAF
BLADE
Made up of soft green tissues.
This tissues are: epidermis, mesophyll, and vein tissues.
EPIDERMISThe outer skin of a leaf.
MESOPHYLLThe middle skin of a leaf.
The veins are the mechanical tissue.
VEINS
CUTIN
Also known as cell wall or wax.
It forms the cuticle which protect plants from water loss, pest and diseases.
GUARD CELLS
They are pair of smalls, green cells around the small pore, the stomata.
STOMATA
They connect the air spaces and cell inside the leaf.
VEINS
Made of long cylindrical cells through which the water and mineral salts from the roots pass to the cells of the leaves.
Chloroplast
A special substances used in the manufacture of the plant food.
It also contain green coloring matter known as chlorophyll.
God bless.
That’s all for
today.
Two functions of LEAF
PHOTOSYNTHESIS
A process when leaf cells containing chlorophyll take in carbon dioxide and water and using sunlight, make sugar and oxygen.
TRANSPIRATION
It is the loss of water from the leaf. This helps to draw water up through the plant from the roots.
FLOWER
The reproductive part of the plant.
Parts of a FLO
WER
STAMEN
The male
part of a flower.
Composed of the anther
where pollen is made and
the thin filament.
PISTIL
The female
part of a flower.
Composed of the stigma,
the thin style and the ovary.
SEPALS
Collectively
called calyx.
They are green and leaf like, compose
the outermost part of the
flower.
They protect the delicate stamen and
pistil when the flower is still a
bud.
PETALS
Collectively
called corolla.
Protect the stamen and
the pistil when the flower is in its early stage
of growth.
Terms to REMEMBER
POLLINATION
Occurs when pollen is
transferred by insects or wind
from the anther to stigma.
Chemicals called enzymes ‘drill’ a channel down through
the style to the ovary where the egg is.
FERTILIZATION
Occurs when the pollen join with the
egg.
GERMINATION
The process when a
seed grows into a
seeding.
CAPILLARY
ACTION
An adhesive attraction
between the water particles
and the vessels inside
the plant.
DIFFUSION
The net movement of a substan
ce.
God bless.
That’s all for
today.
Parts of a SEED
SEED COAT
It protects the
embryo and the
food supply.
EMBRYO
The baby plant.
RADICLE
Part of the embryo that grows into
the primary root.
ENDOSPERM
The supplier of the plant own food.
COTYLEDON
Also known as seed leaf,
absorbs the food in the
endosperm and transports it to the embryo.
DidYou
knowthat
A bean has two
cotyledons. It absorb all
the food supply.
Seeds with two
cotyledons are called
dicotyledons or dicots.
While those with one
cotyledon are called
monocotyledons or
monocots.
God bless.
That’s all for
today.
