Stomata

The main function of stomata is to

Leaves of green plants contain openings known as stomates, which are opened and closed by specialized cells allowing for gas exchange between the leaf and the outside environment. Which phrase best represents the net flow of gases involved in photosynthesis into and out of the leaf through these openings on a sunny day?

• carbon dioxide moves in; oxygen moves out

• carbon dioxide and oxygen move in; ozone moves out

• oxygen moves in; nitrogen moves out

• water and ozone move in; carbon dioxide moves out

Which of the following conditions will favour a most reduced rate of transpiration?

• reduced environmental temperature and high light intensity

• increased environmental temperature and reduced wind speed

• increased relative humidity and reduced wind speed

• reduced relative humidity and increased wind speed

The diffusion of water vapor out of a leaf

• transportation

• transformation

• transpiration

• translocation

What is the primary function of stomata in plant leaves?

• To absorb nutrients from the soil

• To allow carbon dioxide to enter and oxygen and water vapor to exit

• To store water for the plant

• To protect the plant from herbivores
