Answer:
Step-by-step explanation:
First of all, let's discuss the importance of sunlight, or rather sunlight, to plants. Photosynthesis is of paramount importance to the plant kingdom and some members of the protist kingdom (such as algae) because it is with this reaction that these beings acquire food for survival. Photosynthesis, basically, talking about the reaction, these organisms take the sun lights and change it into chemical energy. In general, the organism takes carbon dioxide and water, with the help of sunlight to accelerate this process, get sugar, oxygen and more water. And in this process we have the presence of ATP's, which are like blocks of energy. Without this energy and process, plants and alges can't live, grow and continue their lifes. Now talking about of cellular respiration, it is the inverse of the process of photosynthesis, in which case it absorbs oxygen and releases carbon dioxide. In this process there is the use of ATP's and sugar formation. The cytoplasmic organelle responsible for this respiration is the mitochondria. But in organisms that can't process photosynthesis for the reason they don't have cloroplast, the sun is important for the following reason: With sunlight there is the production of vitamin D. This vitamin is essential for the balance of different organs and functions of the body. Responsible for regulating the absorption of calcium and phosphorus, it keeps the brain running smoothly, and strengthens bones, teeth and muscles and for this reason this assertive is correct "Without the sun, I would be unable to move".
