Q

What do guard cells do

A

They open and close the stomata to regulate the gas exchange

17
Q

What affects the rate of photosynthesis

A

Light Intensity, temperature, Chlorophyll and amount of Carbon Dioxide

18
Q

What are Limiting Factors

A

Limiting Factors mean that it is stopping photosynthesis from happening any faster

19
Q

What can lack of Nutrients cause

A

The chloroplast to become damaged because there is not enough chlorophyll which means the plant won’t be able to photosynthesise properly because it cant absorb enough light
