Photosynthesis

Question 1

What is the process of photosynthesis?

Answer 1

Light energy is absorbed by chlorophyll in the chloroplasts

This energy is then used to convert CO2 and H20 into glucose for respiration - oxygen is a by-product

Question 2

How is CO2 a limiting factor?

Answer 2

Insufficient CO2 means less photsynthesis can happen as there is less CO2 to react with the water

Question 3

How is temperature a limiting factor?

Answer 3

Too hot - No photosynthesis

Too cold - Less photosynthesis

Question 4

How is Light Intensity a limiting factor?

Answer 4

Less energy to react CO2 and H2O with, reaction slows with low light

Question 5

How is the leaf structure adapted for photosynthesis?

Answer 5

They have a large surface area, so they can absorb more sunlight
They are also thin, so CO2 doesn’t have to diffuse far
Stomata allow entrance of CO2 also

Question 6

What are magnesium ions used for in a plant?

Answer 6

Creating chlorophyll

Question 7

What are nitrate ions used for in a plant?

Answer 7

Creating amino acids
