Question

what is lysosomes give the functions of lysosomes

Answer 1

Lysosomes are a type of waste disposal system of the cell. They keep the cell clean by digesting any foreign material as well as worn out cell organelles. They do so by breaking them down into simpler particles. It is possible because they contain powerful digestive enzymes capable of breaking down all organelle material. Hence they cleanse the cell.
Also , if there is a disturbance in cell metabolism , for eg: when the cell gets damaged , Lysosomes burst and their enzymes digest the whole cell , thus , they are called suicidal bags of the cell . 

Answer 2

Lysosomes -

Lysosomes are membrane-bound sacs that are filled with digestive enzymes.

These enzymes are made up of Rough Endoplasmic Reticulum.

Lysosomes are also called suicide bags of a cell because, during the disturbance of cell metabolism or when the cell gets damaged, lysosome may burst and the enzymes may digest their own cell.

Functions of Lysosomes -

→ They help to clean the cell by digesting any foreign material that enters the cell.

→ They remove bacteria or any other material entering the cell.

→ During starvation, it digests stored food contents by autophagy and supplies energy to the cell.
