What is the compromise that stomata accomplish what balance

What is the compromise that stomata accomplish – what balance are they always trying to meet for the maximum productivity of the plant?

Solution

Answer:

Stomata are samll pores present in the leaf of the plants and allow water to evaporate from the leaves (transpiration). And they are the site of CO₂ and O₂ exchange, as they allow the CO₂ to enter into the leaves as required for the process of photosynthesis and release O₂ (the end product of photosynthesis).

The stomata are open during the day time (to take in CO₂ and to evaporate water) and closed in the night (to prevent water loss from the plant when the photosynthesis does not takes place). Thus, they always trying to meet the water content and CO₂-O₂ balance for the maximum productivity of the plants. However, in the conditions of decreased water content, the stomata respond to remain closed in the day time to prevent the water loss. Thus, the photosynthesis stop, as there is no CO₂ intake from the stomata.
