Question

A plant can open or close its stomata in response to environmental conditions. Which best explains how the ability to open and close stomata benefits a plant?

Answer 1

Answer:

There are many environmental factors that affect the opening and closing of stomata, mainly water availability.  

Stomata regulate gas exchange and water flow. The exchange of carbon dioxide between the plant and the  medium is controlled by the opening and closing of stomata. When the stomata open  increases the amount of carbon dioxide that enters the plant, but also  the amount of  water loss increases. For this reason during the night the stomata are closed to avoid unnecessary loss of water.

In dry ecosystems the leaves have fewer stomata to reduce the loss of

water generated by high temperatures.

Answer 2

A plant can open or close its stomata in response to environmental conditions. ... A. During a rainstorm, stomata can be opened to absorb additional water through osmosis. B. During a drought, stomata can be closed to prevent excessive water loss through transpiration.
