Photosynthesis

Question 1

What is photosynthesis?

Answer 1

a process used by green plants to convert light energy to chemical energy which is used as fuel for the organism

Question 2

What are 2 inorganic materials needed for photosynthesis?

Answer 2

carbon dioxide and water

Question 3

what pigment absorbs light energy from the sun?

Answer 3

chlorophyll

Question 4

Where can you find the pigment?

Answer 4

in chloroplasts

Question 5

What are the products of photosynthesis?

Answer 5

glucose,water and oxygen

Question 6

photosynthesis balanced equation?

Answer 6

12h(2)o + 6CO(2) -> C6H12O6 +6O2 + 6H20

Question 7

What do light dependent reactions need?

Answer 7

sun

Question 8

where do light dependent reactions occur?

Answer 8

grana

Question 9

what happens to the water in light dependent reactions?

Answer 9

it splits

Question 10

what is released in light dependent reactions?

Answer 10

oxygen

Question 11

what is light independent reactions also known as?

Answer 11

calvin cycle

Question 12

where do light independent reactions occur?

Answer 12

stroma

Question 13

What part of the plant carries out photosynthesis?

Answer 13

chloroplasts

Question 14

where does co2 come from?

Answer 14

the atmosphere

Question 15

what happens to glucose after it is produced?

Answer 15

• cellular respiration

- produces proteins and cellulose

Question 16

How do leaves maximise photosynthesis?

Answer 16

• they are fat and wide which means a large surface area to absorb light
• thin so gas can reach it
• veins to carry water to and glucose away
• have stomate (holes) to allow gasses to move in and out

Question 17

Limiting factors of photosynthesis?

Answer 17

• amount of light
• co2 level
• temperature
• amount of h20
  pollution coating the leaves
