In this activity you will:

• Learn about the plant parts.• Learn about the process of Photosynthesis.

Parts of the plant:1

2

3

4

1) FLOWER:

Fruits and seeds form inside.

2) Stem:• Stems help

hold plants up.

3) Leaves:

• Where the plant makes food.

4) Roots:• Roots take up water

and other materials that plants need from the soil.

• Roots also hold plants in the soil.

NAME THE PLANT PARTS

Fruits and seeds form inside

Take in water and nutrients from the soil

Carry water and nutrients from the roots to the rest of the plant

Hold the plant in the ground

Where the plant makes food

Holds up the leaves

What is photosynthesis?

• It’s a Process by which plants make their own food.

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

Plants need sunlight for photosynthesis

• Cells in the plant trap light energy from the sun

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

• The plant uses the simple sugars to help it grow

The chlorophyll absorbs the sunlight. Plants’ leaves contain chlorophyllChlorophyll (green color) Chlorophyll is needed for photosynthesis

The chlorophyll processes the ingredients and makes sugar (plant food) and oxygen.

Sugar + Air

O2

Plants have tiny holes in the bottom of each leafThe tiny holes let air go in and out of the leafPlants use a gas in the air called carbon dioxidePlants release oxygen back into the air

CO2

Plants need water for photosynthesis

• Plants get water from the soil

• Roots bring water from the soil to the plant

• Water is needed for the cells of the plant to carry on photosynthesis

Plants and animals need each other to survive.

Animals including humans make the CO2 (carbon dioxide) plants need.They (the plants) make the O2 (oxygen) and food we need.

Plants Need Oxygen to make photosynthesis:

True False

Plants take in water from
