The theory of endosymbiotic origin of chloroplasts has become basal in present-day biology. In this regard, the emergence of eukaryotic photosynthesis has been established as a result of phagocytal capture of cyanobacteria by some ancestral eukaryotic cell. The phenomenon of endosymbiosis is an ...

Plant cells have high concentrations of molecules dissolved in their cytoplasm, which causes water to come into the cell under normal conditions and makes the cell's central vacuole swell and press against the cell wall. With a healthy supply of water, turgor pressure keeps a plant from wilting...
This makes them the most important cell organelles given that plants are the primary producers and the base of all food chains. Depending on the type of plant or algae, the number of chloroplasts in a cell may range from 1 to 100. They are located in the cell cytoplasm and move across...
