Answering the question, when plants close their stomata, plants cannot take in the carbon dioxide they need for photosynthesis. Therefore, the correct answer is A.
Stomata can be defined as tiny openings in plant tissue that allow the exchange of carbon dioxide and oxygen. It is found in plant leaves and stems. There is a presence of some specialized cells within the stomata and the cells are responsible for the opening and closing of the stomatal pores.
<h2>Further Explanation</h2>
Stomata enable plants to absorb carbon dioxide which is important in the process of photosynthesis (the process by which green plant produce their food)
Stomata close during hot or dry conditions to limit the loss of water. In other words, they close when there is a hot or dry condition to reduce water loss.
The plants present on the land possess huge numbers of stomata on their leaves and most of the stomata can be found on the underside of the plant leaves. The position of the stomata also reduces their exposure to heat and wind. They are located on the upper surface of leaves in aquatic plants.
Therefore, when plants close their stomata, plants cannot take in the carbon dioxide they need for photosynthesis.
