Detailed explanation-1: -A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.
Detailed explanation-2: -They clean up the cells. They are the organelles through which oxygen enters the cell.
Detailed explanation-3: -As most high schoolers learn, the lysosome carries out waste disposal and recycling. In a process known as autophagy (meaning “self-eating”), it takes in old cellular components and unneeded large molecules, such as proteins, nucleic acids and sugars, and digests them with the help of enzymes and acids.
Detailed explanation-4: -In particular, lysosomes are formed by the fusion of transport vesicles budded from the trans Golgi network with endosomes, which contain molecules taken up by endocytosis at the plasma membrane.
Detailed explanation-5: -As lysosomes remove unnecessary particles and organelles from cell hence they are called as scavengers of the cells.
