Practice Questions
1.State four uses for the glucose that is produced during photosynthesis
Used in respiration to release energy
Glucose is converted into insoluble starch in storage
Glucose is converted into cellulose and used in cell walls, this will strengthen the plant cell walls.
Glucose is combined with nitrate ions which are absorbed from the soil and used to produce amino acids for protein synthesis.
2. State the advantage of using starch as an energy storage molecule
Starch is insoluble, so it does not have osmotic effects. This means that it will not draw water into or out of cells.
3. Describe how a plant produces protein
Plants use glucose from photosynthesis and nitrate ions absorbed from the soil to make amino acids. These amino acids are then joined together to form proteins.
Factors affecting the rate of photosynthesis
Measuring & calculating rates of photosynthesis
Inverse square law and photosynthesis
Economics of enhancing the conditions in greenhouses
Investigating the effect of light intensity on the rate of photosynthesis
