Structural organization of chloroplast is signified by the presence of double membrane envelope and soluble phase, the stroma, and an internal membrane system, the thylakoids. Both thylakoid and stromal systems are committed for light reaction and carbon dioxide fixation respectively. Chloroplast attains diversified shapes. Higher plants exhibit lens shaped chloroplasts in their cytosol. The size measures anywhere between 5 and [...]
