6CO2 + 6H2O -> C6H12O6 + 6O2

3

How is carbon dioxide obtained to be used in photosynthesis?

It is obtained from the atmosphere via diffusion through the stomata

What is glucose stored as?

Insoluble starch or sugar

8

What is glucose used to make and do in a plant?

Fats for storage
Cellulose to strengthen the cell wall

Respiration

9

What is the test for photosynthesis?

Use iodine to test for starch

10

What is a variegated plant?

One that doesn't photosynthesis everywhere
As chlorophyll and starch are only found in some parts of the leaf

11

What are the three limiting factors of photosynthesis?

Light intensity
Carbon Dioxide concentration
Temperature

12

What are also used to produce proteins in plants?

Nitrate ions
Absorbed from the soil
