In plants, the opening and closing of stomata balance water loss with the need for _____________?

Question

Would the answer be carbon dioxide?

Answer 1

Carbon dioxide is what is needed by the cells.---------What do Stomata do?

Stomata must open to admit CO2 into the leaf for photosynthesis, but when they open, they allow water vapor to diffuse out of the leaf. Thus, stomata must open enough to support photosynthesis, but they must at the same time prevent excessive water loss. This dilemma has been formalized as a constrained optimization problem.

How do Stomata do it?

Guard cells have complex sensory and signal transduction machinery that allows them to respond to a variety of factor such as light, CO2, and water stress. Guard cells change size and shape by altering their solute concentration so that water flows in or out by osmosis.

Answer 2

how about you get a biology textbook and LEARN about how plants work?

asking all your homework questions here IS NOT going to help you understand what's going on!!!!
