Chloroplast cell.

Photosynthesis in Prokaryotes. The two parts of photosynthesis—the light-dependent reactions and the Calvin cycle—have been described, as they take place in chloroplasts. However, prokaryotes, such as cyanobacteria, lack membrane-bound organelles (including chloroplasts). Prokaryotic photosynthetic organisms have infoldings …Chloroplasts and Photosynthesis - Molecular Biology of the Cell - NCBI Bookshelf All animals and most microorganisms rely on the continual uptake of large amounts of organic compounds from their environment. These compounds are used to provide both the carbon skeletons for biosynthesis and the metabolic energy that drives cellular processes. A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape. In cell division mitochondria and chloroplasts have to be duplicated, their genomes replicated and then the population of mitochondria and chloroplasts segregated to daughter cells. During reproduction these two organelles and their genomes in most cases have to be transmitted to only female gametes, for subsequent zygote formation [ 4 ].
