Description

Chloroplasts represent the most prominent members of a diverse group of essential organelles referred to collectively as the plastids. Plastids are a heterogeneous family of organelles found ubiquitously in plant and algal cells. Chloroplasts perform a variety of biochemical functions within plant cells. They contain the green pigment chlorophyll and are responsible for the light-harvesting and carbon-fixation reactions of photosynthesis, as well as for the synthesis of many essential metabolites, such as fatty acids and amino acids. Other members of the plastid family include the Amyloplasts, which contain large quantities of starch and play important roles in energy storage and gravitropism, and the Chromoplasts, which accumulate the red-orange-yellow Carotenoid pigments and so act as attractants in flowers and fruits. The [...]
