What is Exocytosis ?
The process in which cell transports unwanted materials from the cell is known as exocytosis. The materials which are transported in this process are waste materials like undigested remains, materials needing to produce the cell wall. This type of material are packed into a vesicle and they are directed to the plasma membrane. When these vesicle came in touch with the plasma membrane they releases those waste in the external environment. They also transport the protein and polysaccharides into the cell. Exocytosis is used by plants to release nectar to attract pollinators.
Difference Between Exocytosis And Endocytosis
Cell consists of four types of transportation mechanism – Diffusion, active transport, osmosis and bulk transport. The two types of bulk transportation mechanism are known as Exocytosis and Endocytosis. They transport big particles through the plasma membrane from the cell. Exocytosis is the process in which cell transports unwanted materials from the cell while Endocytosis is the transportation of large particles which cannot enter the cell through the non-polar membrane. Endocytosis involves in taking nutrients into the cell whereas exocytosis involves in removing waste from the cell.
