A chloroplast.

The alga already has a chloroplast with two membranes as well as a nucleus and other organelles. Since the host cell only needs the energy from the chloroplast, the other captured organelles degenerate and eventually disappear. However, the membranes often remain and the chloroplast is left with four membranes, rather than two.Introduction. The chloroplast is a hallmark organelle of eukaryotic photosynthetic organisms. Over 85% of global biological light energy capture, CO 2 fixation, and O 2 production happens in chloroplasts, driving the Earth’s biochemistry. 1, 2 In addition to photosynthesis, the chloroplast has essential roles in key cellular processes including amino acid synthesis, 3 starch synthesis, 4 ...Chlorophyll is a key component in the process of photosynthesis, which sustains plant life and produces oxygen for the entire planet.
