Photosynthesis

1
Photosynthesis

• Grade 7

2
The student will

• Learn what photosynthesis is and how it helps
  plants.
• Learn what a plant needs for photosynthesis.

3
What is photosynthesis?

• Plants make their own food. This process is
  called photosynthesis.

4
Where does photosynthesis occur?

• Photosynthesis occurs in the leaves of a plant.

5
What is needed for photosynthesis to occur?

• Light is needed for photosynthesis to occur. The
  plants leaves use the light to make a sugar
  called glucose.

6
Why do plants need glucose?

• Glucose is the food for the plant. It gives the
  plant energy to grow.

7
How much glucose does a plant make?

• Plants make enough glucose to be used during the
  night and on cloudy days when they dont get
  sunlight. The extra glucose is stored in the
  plants leaves and other parts.

8
How does photosynthesis help us?

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

9
What is Cellular Respiration?

• The release of chemical energy for use by cells.

10
Describe Cellular Respiration

• The breakdown of glucose molecules to release
  energy
• Takes place in all living things
• Is a step by step process
