B8: Photosynthesis

Question 1

What are 5 ways that glucose produced from photosynthesis may be used?

Answer 1

Respiration, converted into insoluble starch for storage, used to produce fats/oil for storage, production of cellulose and produce amino acids for protein synthesis

Question 2

What type of reaction is photosynthesis?

Answer 2

Endothermic

Question 3

Why is starch a good form of storage?

Answer 3

Compact, easy to be broken down and insoluble, so water won’t be drawn into cell

Question 4

How are amino acids formed?

Answer 4

Glucose combined with nitrate ions

Question 5

What factors affect the rate of photosynthesis?

Answer 5

Light intensity, temperature, carbon dioxide concentration and chlorophyll concentration

Question 6

What would affect the levels of chlorophyll in a plant?

Answer 6

Disease, environmental stress or lack of nutrients

Question 7

What would farmers do in colder climates to increase the rate of photosynthesis?

Answer 7

Place plants in greenhouses, trapping sun’s heat, as well as artificial light
