Question

(d) Glucose is a product of photosynthesis. Give three uses which green plants make of
glucose.
​

Answer 1

Answer:

1. Plant energy storage.- Thousands of glucose molecules can be linked together to form the complex carbohydrate starch. Starch is stored inside plant cells as grains.
2. Production of other types of food- Glucose is an example of a carbohydrate - it contains the chemical elements carbon, hydrogen and oxygen. Plant cells can convert the sugar into another type of energy storage molecule - fat.

Glucose is an example of a carbohydrate - it contains the chemical elements carbon, hydrogen and oxygen. Plant cells can convert the sugar into another type of energy storage molecule - fat.Plant cells can also combine sugars with nitrates to make amino acids and use these to produce proteins.

3. Plant building material-Thousands of glucose molecules can be linked together to form the complex carbohydrate cellulose. Cellulose is a very tough molecule that is used to build the cell wall of plant cells.

Answer 2

Light energy is absorbed by the chlorophyll in the chloroplast the energy is used to carbondioxide from the air and water from the soil into the simple sugar glucose and the by-product oxygen.3.They use it for respiration to provide energy for cell functions such as growth and reproduction.
