Answer 2

Answer:

Guard cells play in maintaining optimum water level in plant by regulating the opening and the closing of the stomata.  

Explanation:

Transpiration and respiration are 2 very important processes that take place through the stomata. Transpiration is a process through which the plant sweats through its stomata, that is the release of excess water in the leaves through formation of water vapour into the atmosphere, thus balancing the plant and maintaining its optimum levels.
