Select all that are true regarding gas exchange in a vascular plant.
*Guard cells regulate whether stomata are open or closed based on availability of water in the plant.
*Plants that live in dry environments have adaptations such as reduced leaves (such as needle-shaped leaves) to reduce water loss as much as possible.
*When stomata are closed, the plant is not able to exchange oxygen and carbon dioxide gas with the atmosphere.
*Oxygen gas from the atmosphere enters leaf stomata, and carbon dioxide gas leaves.
*Stomata are open when a plant is low on water, and closed when a plant has plenty of water.
*Plants close their stomata to reduce water loss.
*Guard cells regulate whether stomata are open or closed based on availability of sugars in the plant.
*Transpiration is loss of water vapor from leaves.
