- Photosythesis
- Carbon dioxide + water-> glucose + oxygen
- Light energy is absorbed by chlorophyll in chloroplasts
- plant cells and algae
- Oxygen= by-product that is given off as a gas
- Limiting factors
- Light Intensity
- On graph if gradient is positive then it is a limiting factor. When gradient = 0 there is another limiting factor.
- Carbon dioxide concentration
- Temperature
- Enzymes denature if temperature is too high

- Carbon dioxide concentration
- Light Intensity
- Use of glucose in plants
- Produces cellulose; makes up cell walls
- Produces fats and oils
- Makes proteins
- Nitrogen is also needed to make proteins
- Nitrate ions are absorbed from the soil.
- Nitrogen is also needed to make proteins
- Can be converted into starch for storage
- Can be used during respiration
- Carbon dioxide + water-> glucose + oxygen
