Lysosomes – Definition , Functions , Location and Importance of Lysosomes

What are lysosomes?

Lysosomes are membrane bound cell filled with digestive enzymes  which helps in waste disposal system of the cell.

Where are lysosomes located?

Lysosomes are found in  Eukaryotic cell. They are generally found in animal cell and not commonly found in plant cells. Lysosomes are enzyme filled membrane bound sacs that are found in cytosol of the cytoplasm of an Eukaryotic cell.

What are the functions of lysosomes? What do lysosome digest and destroy?

Lysosomes have following functions

  • It is the waste disposal system of the cell .
  • Lysosomes clean the cell  by digesting  any foreign material as well as  worn out cell organelles.
  • Lysosome protects the cell  from bacteria by breaking them up into small pieces.
  • Lysosomes help in disposal all of dead cells in the tissues .

What would happen to the cell without lysosomes or  Why lysosome are important?

Lysosomes play an important role the animal cell.   It is the waste disposal system of animal cell.

  • It digest the worn out cell organelles, foreign material like  bacteria entering in the cell.
  • It has powerful digestive enzyme capable of Breaking Down all organic matter .
  • If there were no lysosomes the cell will not able to digest food .
  • Without Lysosomes there will be accumulation of waste like worn out cell organelles in the cell.
  • Cell will not get protected from  harmful bacteria and viruses.

Eventually the cell will not able to survive.

What prevents lysosome from digesting themselves ?

The lysosome membrane is made up of lipids and proteins  which prevents the internal  enzymes from digesting the cell itself.

Why are lysosomes known as suicidal bags ?

Lysosomes are known as suicidal bags because when cells get damaged during the disturbance in cellular metabolism lysosomes may burst and the digestive enzyme does release digest their own cell.
