Photosynthesis

Question 1

Process of photosynthesis

Answer 1

Plants trapping energy from light, which is transferred into molecules of sugar (glucose)

Question 2

Word equation for photosynthesis

Answer 2

Carbon dioxide+water -> glucose+oxygen

Question 3

What kind of reaction is photosynthesis

Answer 3

Endothermic

Question 4

Where in a plant cell does photosynthesis occur

Answer 4

In chloroplasts, which have chlorophyll that traps the energy from sunlight

Question 5

Starch

Answer 5

a polymer of linked glucose molecules

Question 6

What is starch used for

Answer 6

It stays in the chloroplasts until photosynthesis stops. It is then broken down into simpler substances which are move into the cytoplasm to produce sucrose

Question 7

How have leaves adapted for photosynthesis

Answer 7

Broad and flat. The top layer is filled with palisade cells which are filled with chloroplasts. This helps the plant trap more sunlight

Question 8

Stomata

Answer 8

small pores in the leaf which allow carbon dioxide to diffuse into the leaf.

Question 9

How can a reduced concentration of air molecules affect a plant

Answer 9

It lowers the rate of photosynthesis

Question 10

How can an increase in light intensity or temperature affect a plant

Answer 10

It increases the rate of photosynthesis
