Do they eat???

Have you ever think

Where do plants get

the energy they

need to grow?

Do they drink???

Photosynthesis is the process by which

plants use energy from the sun to transform

carbon dioxide and water into a storable

form of energy, glucose.

Plants use some of their own stored

energy to support their life processes such

as growth and reproduction.

Animals take energy that plants store intheir tissues. Animals and humans, rely on

the carbohydrates found in plant roots,

stems, leaves, and fruits as their primary

source of energy.

The starting point for this transfer of

energy is photosynthesis. This is why plants

are called producers.

Shape

Flattened leaf has largesurface to receive more

light

Thin leaf for light to reach

lower layers and for

diffusion of gases

Palisade

mesophyll

Found below the upperepidermis

The cells are column-

shaped and contain many

chloroplast

They are closely packedtogether vertically to

receive maximum sunlight

The cellular air-space

permit an

uninterrupted

exchange of gases

between leaf and the

atmosphere

v

Stomata is site of gasexchange between leaf

and surroundings.

During day, carbon

dioxide diffuse into leaf

for photosynthesis and

oxygen diffuse out. Theguard cell regulate the

size of stomatal pore

Stomata

Each stomata consist of a

stomatal pore enclosed bya pair of guard cell

containing chloroplast

vFine network of veins in

the leaf

Vascular

tissue

Xylem transport water and

mineral ions to the leaf

Phloem transport organic

molecule produced by

photosynthesis from leaf

to other part of plant.

exchange between leaf and

surroundings. During day,

carbon dioxide diffuse into

leaf for photosynthesis and

oxygen diffuse out. The guard

and other eukaryotic organism thatconduct photosynthesis.

Carbohydrate : an organic compound

with general formula Cm(H2O)n, that is,

consisting only of carbon, hydrogen and

oxygen.Producer :The starting point for this
