(7 cards)
1
Q
Where do leaves take in CO2?
A

2
Q
Which direction does the CO2 move in?
A
Into the plant.
3
Q
Which has a faster reaction rate - photosynthesis or respiration?
A
ROR Photosynthesis > ROR Respiration
4
Q
What does the net exchange of CO2 and Oxygen in plants depend on?
A
The intensity of light
5
Q
How is a leaf adapted for effective gas exchange?
A
- leaf is thin; short diffusion distance
- stomata allows diffusion of gases
6
Q
The origin of CO2 and Oxygen is from…
A
- The waste products of metabolism
- Their loss from the stomata
7
Q
