Bio 1108 Plant Transport

If a plant closes its stomata, this means...

• it cannot take in carbon dioxide for photosynthesis

• it loses water by transpiration

• it will become turgid

• it can take in more oxygen for respiration

Which conditions speed up the rate of transpiration?

• hot dry and windy

• hot wet and windy

• cold wet and not windy

• cold dry and windy

How does water get from the leaf to the atmosphere?

• it moves by osmosis into the air spaces and diffuses through the stomata

• it diffuses into the air spaces and evaporates through the stomata

• it evaporates into the air spaces and diffuses through the stomata

• it moves by active transport into the air spaces and evaporates through the stomata
