Water, light
Carbon dioxide, chlorophyll, water, oxygen
What are the products of photosynthesis? (Select all that apply)
Oxygen
Sucrose

Water
What term is used to describe factor present in the environment in such short supply that it restricts life process?
(a)
How does carbon dioxide get into plant?
Through the palisade mesophyll cells
Through the stomata

(a)
What control the opening and closing of stomata?
(a)
Which is true about stomata?
Open during day and close at night
Open during both day and night
Open at night and close during day
Always close
When do plants carry out respiration?
During day
At night
When there is no sunlight
All the time
Why do stomata close in very hot, dry conditions?
To prevent a high rate of transpiration/water loss
To prevent plants drying out
Because there is no carbon dioxide
To prevent oxygen diffusing out

True
False
