1. Photosynthesis

2. Plants are producers because they
produce their own food in a process
called:

3. This process happens in
the leaf of the plant.

4. For photosynthesis plants need:
Light
 The plant’s leaves use the light to make a sugar
called glucose.

5. Air
 The plants need carbon dioxide and produce
oxygen.

6.  Water
 The plants need water to produce their own food.

7. What is Glucose?
Glucose is the food for the
plant.
It gives the plant energy to
grow.

8. How much glucose does a plant make?
Plants make enough
glucose to be used
during the night and
on cloudy days when
they don’t get
sunlight. The extra
glucose is stored.

9.  During the process of photosynthesis, oxygen is
produced. We use this oxygen to breathe.

11. Plants are:
a) producers
b) consumers
c) decomposers
