25. The organelle that carries out the reactions of photosynthesis is the chloroplast. Chloroplasts are found in plant cells and some algae, and they contain the pigment chlorophyll, which is essential for capturing light energy and converting it into chemical energy during photosynthesis.26. The purpose of the pigment chlorophyll is to absorb light energy, primarily from the sun, and convert it into chemical energy during the process of photosynthesis. Chlorophyll absorbs light most efficiently in the blue and red wavelengths, which is why plants appear green, as they reflect green light.27. Photosynthesis and cellular respiration are alike in that they both involve the conversion of energy from one form to another. In photosynthesis, light energy is converted into chemical energy in the form of glucose, while in cellular respiration, the chemical energy stored in glucose is converted into a form of energy that can be used by cells, known as ATP.28. Photosynthesis and cellular respiration are different in several ways. Photosynthesis occurs in the chloroplasts of plant cells and some algae, while cellular respiration occurs in the mitochondria of both plant and animal cells. Photosynthesis requires light energy and produces glucose and oxygen as products, while cellular respiration does not require light and uses glucose and oxygen as reactants to produce carbon dioxide and water as products. Additionally, photosynthesis is an anabolic process that builds complex molecules from simpler ones, while cellular respiration is a catabolic process that breaks down complex molecules into simpler ones.
