Plants Exchange Gases By Diffusion Flashcards
1
Q
What do plants do when they photosynthesise?
A
They use up CO2 from the atmosphere and produce O2 as a waste product
2
Q
What do plants to when they respire?
A
They use up O2, and produce CO2 as a waste product
3
Q
Why is there hardly any CO2 inside the leaf?
A
When the plant is photosynthesising it uses up lots of CO2
4
Q
How is this good (lack of CO2 in leaf)?
A
It makes more CO2 move into the leaf by diffusion
5
Q
What is being made as a waste product of photosynthesis?
A
Lots of O2
6
Q
Where happens to it? (Lots of O2)
A
Some is used in respiration, and the rest diffuses out the stomata
