WebbThe leaf chloroplast - origin and architecture In plants photosynthesis takes place in mesophyll and bundle sheath cells, the major components of leaves. More specifically it takes place in a cellular organelle called the chloroplast, of which there are ~120 in a typical mature Arabidopsis thaliana leaf mesophyll cell (Buchanan et al., 2002). WebbThe cellular components are called cell organelles. These cell organelles include both membrane and non-membrane bound organelles, present within the cells and are distinct in their structures and functions. They coordinate and function efficiently for the normal functioning of the cell. A few of them function by providing shape and support ...

Chloroplasts are one of many types of organelles in the plant cell. They are considered to have evolved from endosymbiotic cyanobacteria. Mitochondria are thought to have come from a similar endosymbiosis event, where an aerobic prokaryote was engulfed.
