Answer:
Xylem transports water, stomata take in carbon dioxide, and chlorophyll absorbs sunlight.
Explanation:
Photosynthesis is a vital process for the plant and is carried out thanks to xylem (it transports water), stomata (it captures CO2) and chlorophyll (it captures sunlight).
The transport of water in the plants is done mainly by the xylem route, this route is simpler when compared to the root, having less resistance, thus it has less pressure gradient necessary to transport water from the soil to the leaves. Xylem transport is much more efficient than cell-to-cell water transport. As we know, water is very important in the process of photosynthesis, so we can emphasize the importance of the xylem.
The main function of a stoma is to control the entry and exit of gases, so we can conclude that they are directly related to the performance of the photosynthesis process since CO2 is captured (important for photosynthesis to occur) and the release of oxygen. Stomata are found mainly in leaves and stems, being absent in roots.
Chlorophyll is the pigment responsible for capturing light and ensuring that photosynthetic organisms are able to produce their food through the process of photosynthesis, because it is able to capture sunlight. Therefore, it is essential for the maintenance of oxygen available on the planet. It is worth mentioning that, in addition, this pigment has commercial importance, being used, for example, as an antioxidant and coloring agent in foods.
