Introduction
The basic unit of life is essentially the cell. A cell membrane surrounds all the cells. The cell membrane is thus semi permeable hence this allows certain substances to pass and blocking others into the cell. This cell membrane is composed of phospholipids that are a double layer embedded in proteins. Plant cells on their part contain an additional layer called cell wall that surrounds them. An organelle in cell biology is actually a specialized subunit or structure, which is found within a cell and has a specific function. Therefore, a cell organelle refers to a membrane bound structure or compartment in a cell which performs a ...
