Document Summary
11 x 1013 kg of carbon dioxide is converted into organic molecules per year. Is fixed by photosynthetic microorganisms called phytoplankton, which inhibit marine environments. This is because they are nutrient poor and are deficient in iron. Colder water around the poles are nutrient rich and support a large phytoplankton biomass. Synthetic organisms use light energy to synthesize organic molecules and are thus classified as photoautotrophs. Photosynthesis is present in b and e, but not a. Instead, archaea use phototrophy, which include any process that converts light energy into chemical energy. Photosynthesis is composed of light reactions and the calvin"s cycle. An outer membrane covers the entire surface of the organelle, whereas an inner membrane lies just inside the outer membrane. Between the outer and inner membranes is the intermembrane compartment. The aqueous environment within the inner membrane is the stroma of the chloroplast.
