Summary Introduction
To argue:
Against a proposal given by a candidate that the mitochondria and chloroplast should be classified in the endomembrane system.
Introduction:
Mitochondria are membrane bound organelle which is also known as “power house of the cell”. It is present in almost all cells except RBCs. The structure of mitochondria includes outer and inner membranes made of lipid and proteins. The chloroplast is a lens shaped in structure and enveloped in membranes called as stroma which contains DNA, ribosomes and enzymes. Flat and connected sacs known as thylakoid are present in units known as granum which contains chlorophyll. The chlorophyll captures the sunlight and converts and stores it in the form of ATP.
