The role of the guard cell is to

control the movement of water vapour & gases

help control the temperature of the plant

control how much water enters the leaf

control how much glucose is stored

What is chlorophyll's main function?

to capture energy from sunlight for photosynthesis

to blend into their environment

Which is NOT a reason why we should care about photosynthesis?

It creates food for the plants, which then feed animals.

Without it, we wouldn't be able to breathe oxygen.

It uses up greenhouse gas CO 2 in the atmosphere.

Which of the following is the correct equation for PHOTOSYNTHESIS?

CO 2 + light + H 2 O --> O 2 + Sugar

CO 2 + sugar + H 2 O --> O 2 + light

O2 + light + H 2 O --> CO 2 + Sugar

CO 2 + O 2 + H 2 O --> Light+ Sugar

Which statement about photosynthesis is correct?

Plants get the energy they need for photosynthesis from sunlight.

Plants get the energy they need for photosynthesis from water.

Plants get the energy they need for photosynthesis from soil.

Plants get the energy they need for photosynthesis from carbon dioxide.

How does photosynthesis benefit heterotrophs?

It creates a source of energy they can eat.

It adds carbon dioxide to the air.
