Plants Produce

Food

Every organism on Earth needs energy to live and grow.

The primary source of all

life energy on Earth’s is the

Sun.

But animals can’t eat

sunlight.

Animals can only get energy by eating (consuming)

other organisms (plants or animals).

Animals are consumers.

Only green plants can produce food.

Plants are producers. They make food.

Only plants can make food.

Plants make food in their

leaves.

A green material in leaves called

chlorophyll (klor oh fil)

turns light energy from the sun into chemical energy (sugar).

Producers convert sunlight energy into a

chemical energy (glucose; sugar; food)

that animals must have to live.

Sugar made in the leaves moves through tubes to other parts of the plant..

Plants get the CO2, carbon dioxide, they need from the air.

Plants get the water they need from soil with their

roots.

Water goes through tubes in the stem to get to the leaves.

The process of plants turning sunlight energy, CO2, and water into chemical energy (food, sugar) is called …

Plants “put food together” using light energy in the process called photosynthesis.

Plants take (CO2) carbon dioxide into their leaves and use it during photosynthesis.

CO2

Plants release (throw away)

oxygen as a waste product as they make food.

oxygen

Plants release (throw away)

oxygen as a waste product as they make

food. Oxygen is a gas that makes up 21% of the air.

Plants can’t live without CO2 and must release oxygen.

Animals can’t live without oxygen and must release CO2.

This is a very important

balance for life on Earth.

Now, let’s see how much you remember about producers and photosynthesis.

Which type of organisms must eat other organisms?

Consumers (animals) must eat other organisms.

Which type of organisms can make food?

Only producers (plants)

can make food.

What is the name of the process in which plants (producers) make food?

Photosynthesis is the process in which plants make food.

Review:

In what part of the plant is sunlight turned into food? (glucose; sugar)

Leaves are the part of the plant where food is made during photosynthesis.

One leaf

Three leaves

What is the name for the energy chemical that plants and animals need to live and grow?

Hint:Plants make it in their leaves from sunlight, CO2 and water.

Sugar or glucose is the name for the energy chemical that plants and animals need to live and grow.

Plants move materials through a

system of tubes.

Xylem (zy lem)

tubes carry water and nutrients from roots to the leaves.

Phloem (FLO em)

are the tubes that carry

sap (sugar and water)

from leaves to every part of the plant.

Organisms have system of tubes to transport materials.
