Photosynthesis

In this activity you will: Learn about the process of photosynthesis Write a paragraph describing how plants

use photosynthesis to live and grow

Plants need energy to grow Plants need energy to grow Plants get energy from the sun Plants use energy to carry on the process

of photosynthesis

Chlorophyll is needed for photosynthesis

Chlorophyll is a green material in plants that traps light energy

Chlorophyll is located in long, green cells

Plants get their green color from chlorophyll

Chlorophyll is needed for photosynthesis

Plants need air for photosynthesis Plants have tiny holes in the bottom of

each leaf The tiny holes let air go in and out of the

leaf Plants use a gas in the air called carbon

dioxide Plants release oxygen back into the air

Plants need water for photosynthesis Plants get water from the soil Roots bring water from the soil to the

plant Veins in each leaf carry water

throughout the plan Water is needed for the cells of the plant

to carry on photosynthesis

Plants need sunlight for photosynthesis

Cells in the plant trap light energy from the sun

Light energy helps change carbon dioxide and water to a simple sugar in plants

The plant uses the simple sugars to help it grow

Photosynthesis helps plants live and grow!

Photosynthesis is the process by which plants trap the sun’s energy

Plants use the sun’s energy to change carbon dioxide and water into sugar

Writing Activity Explain how plants use photosynthesis to

live and grow.
