WHAT IS THE FUNCTION OF LYSOSOMES?

Lysosomes are membrane bound vesicle which contain powerful enzymes capable of digesting all organic material.

Lysosome is an organelle in eukaryotic cytoplasm. The lysosomes are small unit membrane – bound sacs that store acid hydrolases. They contain powerful enzymes capable of digesting or breaking down all organic material. They digest food, foreign bodies and intracellular debris and recycle cell components.

 

If lysosome is absent,

  •  The cell start breakdown automatically. (Lysosome’s can protect the cell from self dissolution).
  • Bacteria like microbe can enter into the cell and spoil it. (Lysosome can digest the microbe.)
  • Cell debris cannot be removed. (Lysosome helps for cellular digestion.)

 

More to Know:

  • Lysosomes are found practically in all animal cells. They are absent in plant cells and very rarely they present. They vary in shape, size and number per cell and appear to operate with slight differences in cells of yeast, higher plants and mammals. Though lysosomes present in all animal cells with the exception, they are absent in RBCs. Also absent in few plant cells. Example: Yeast, Fungi and green algae.

they are the suicidal bags of the cell, ie, they contain a hydrolytic enzyme that destroys the worn out or damaged organelles and even the foreign material entering the cell. if the ans helps u , pl give thumps up

Lysosomes are the cell's waste disposal system and can break up anything. They digest almost everything. One exception is asbestos. They are used for the digestion of macromolecules from phagocytosis (ingestion of other dying cells or larger extracellular material, like foreign invading microbes), endocytosis (where receptor proteins are recycled from the cell surface), and autophagy (where in old or unneeded organelles or proteins, or microbes that have invaded the cytoplasm are delivered to the lysosome). Autophagy may also lead to autophagic cell death, a form of programmed self-destruction, or autolysis, of the cell, which means that the cell is digesting itself.

Other functions include digesting foreign bacteria (or other forms of waste) that invade a cell and helping repair damage to the plasma membrane by serving as a membrane patch, sealing the wound. In the past, lysosomes were thought to kill cells that are no longer wanted, such as those in the tails of tadpoles or in the web from the fingers of a 3- to 6-month-old fetus. While lysosomes digest some materials in this process, it is actually accomplished through programmed cell death
