In respiration you take in glucose and oxygen and release CO2 and water. Also in the process energy is released. So the answer is B.
<span>Because the plant interacts with light to absorb only certain wavelengths, pigments are useful to plants and other autotrophs --organisms which make their own food using photosynthesis. In plants, algae, and cyanobacteria, pigments are the means by which the energy of sunlight is captured for photosynthesis.</span>
Algae has very similar structures with land plants. However, these structures are not as quite complex as land plants. For example, algae have chloroplast a, which is also found in plants. Algae can also go through photosynthesis, but not as well as gymnosperm/angiosperm, or anything with a vascular tissue.
