Lysosome
- Lysosomes are membrane-bound sacs filled with digestive enzymes.
- Foreign materials entering the cell, such as bacteria or food, as well as old organelles end up in the lysosomes, which break complex substances into simpler substances.
- During the disturbance in cellular metabolism, for example, when the cell gets damaged, lysosomes may burst and the enzymes digest their own cell. Therefore, lysosomes are also known as the 'suicide bags' of a cell.
- The cytoplasm is the fluid content inside the plasma membrane. It also contains many specialised cell organelles. Each of these organelles performs a specific function for the cell.
- The endoplasmic reticulum (ER) is a large network of membrane-bound tubes and sheets. It looks like long tubules or round or oblong bags (vesicles).There are two types of ER- rough endoplasmic reticulum (RER) andsmooth endoplasmic reticulum (SER). The ribosomes, which are present in all active cells, are the sites of protein manufacture.
- The SER helps in the manufacture of fat molecules, or lipids, important for cell function. Some of these proteins and lipids help in building the cell membrane. This process is known as membrane biogenesis. Some other proteins and lipids function as enzymes and hormones.
- The Golgi apparatus, first described byCamillo Golgi,consists of a system of membrane-bound vesicles (flattened sacs) arranged approximately parallel to each other in stacks called cisterns.Its functions includethe storage, modification and packaging of products in vesicles. The Golgi apparatus is also involved in theformation of lysosomes.
