WebThe chloroplast from higher plants can be a large and abundant organelle that is green in color and is the site of photosynthesis in the organism. Photosynthetic reactions occur in and on the internal membranes of the chloroplast and involve two light absorption steps (i.e., the light reactions). WebChloroplasts are the photosynthetic organelles of green algae and plants. Owing to their endosymbiotic origin, they contain their own genome with about 100 genes. Compared with their cyanobacterial ancestors, chloroplasts have lost most of their genes, due to either gene loss or transfer to the nucleus.

WebMay 25, 2024 · These two molecules are not only in plants, as animals use them as well. A Recipe for Energy Plants need water to make NADPH. This water is broken apart to release electrons (negatively charged subatomic particles). When water is broken it also creates oxygen, a gas that we all breathe. WebIn this case, the thylakoid membrane (the 3rd membrane of chloroplasts) encloses the lumen. The lumen would contain all of the reactants and intermediates of the light-dependent reactions.
