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.
