Question 1

Photosynthesis

Answer 1

Green plants make their own food by photosynthesis
2 stage process that uses light energy from the sun
Enzyme controlled reaction (affected by temperature)

Question 2

Photosynthesis Eqation

Answer 2

Carbon dioxide +water -light chlorophyll = glucose oxygen

Question 3

4 stages of light reaction(stage1)

Answer 3

1)light energy is trapped by chlorophyll in the chloroplasts
2)light energy is converted into chemical energy which is used to generate atp
3)water is split to produce hydrogen/oxygen
4)oxygen diffuses from the cell

Question 4

Stage 2 - Carbon fixation (2)

Answer 4

1) Through enzyme controlled reactions carbon dioxide and hydrogen are chemically joined together usuing ATP
2)Sugar/Glucose is produced

Question 5

Limiting factors of Photosynthesis

Answer 5

Light intensity
Temperature
Carbon dioxide concentration
