Essential Question What does a plant need to
make food?
4
Plants make food through a process called
photosynthesis
5
During photosynthesis, a plant takes in
sunlight, water, and carbon dioxide.
CO 2
6
The water and carbon dioxide combine to form a
kind of sugar.
7
The sun provides the light energy that plants
need to make food.
8
During photosynthesis, plants also make oxygen.
The oxygen is given off into the air through
the leaves.
9
Plants get their green color from chlorophyll.
Chlorophyll helps plants use energy from the sun
to make food.
10
Plants need light to make food. A plant that gets
enough light, water, and carbon dioxide grows
into a healthy plant.
11
Name four things a plant needs for photosynthesis.
water
air
sunlight
chlorophyll
12
How do plants use the food they make?
13
Plants use some of the food they make to grow
bigger and to make seeds.
