Why would the rate of photosynthesis slow down if the stomata are closed?

• Oxygen would not be able to enter the leaf

• Oxygen would not be able to leave the leaf

• Carbon dioxide would not be able to enter the leaf

• Carbon dioxide would not be able to leave the leaf.

What conditions cause stomata to close?

• When there is plenty of water for the plant

• When it is hot and dry to prevent water loss

• When it is windy to support the leaves

• When it is cold to keep in heat.
