1

Photosynthesis

Chemical reaction where green plants make their own food
Occurs in chloroplast

2

First stage

Light reactions
Light energy is trapped by chlorophyll in the chloroplast and is converted to chemical energy to make atp

3

What happens in light reactions

Water molecules are split to produce hydrogen and oxygen and extra oxygen is diffused our cell

4

Carbon fixation

Hydrogen from light reactions combined with co2 to make sugar
ATP is used in production of sugar
Sugar Available for respiration
Sugar not used can turn into start heat or cellulose

5

Start by

Acts as storage of energy

6

Cellulose

Structural component
Makes up cell wall

7

Limiting factors

Temperature
Light intensity
Co2 concentration

8

Word equation

Light energy
Co2+water————-glucose+o2
Chlorophyll
