Topic 11 - Photosynthesis

Question 1

What is the word equation for photosynthesis

Answer 1

Carbon dioxide + water —> glucose + oxygen

Question 2

What is the symbol equation for photosynthesis

Answer 2

6co2 + 6h2o —> c6h12o6 +6o2

Question 3

What is the endothermic reaction that happens in plants

Answer 3

When energy is transferred from the environment to the chloroplasts by light

Question 4

They glucose produced in photosynthesis can be used for

Answer 4

Respiration
Converted into insoluble starch for storage
Fat or oil for storage
Cellulose
Amino acids for protein synthesis

Question 5

How does the amount of chlorophyll affect rate of photosynthesis

Answer 5

Plants that do not get much light make more chlorophyll to make it up

Question 6

How does light intensity affect rate of photosynthesis

Answer 6

Without enough light a plant cannot photosynthesise very quickly reducing the rate

Question 7

How does the concentration of co2 affect the rate of photosynthesis

Answer 7

If the concentration increases then the rate increases

Question 8

How does temperature affect rate of photosynthesis

Answer 8

At low temperature the rate of photosynthesis is limited by the number of molecular collisions between enzymes and substrate
