Question

Why are lysosomes also known as scavengers of the cells?
(a)Lysosomes are capable of removing the cell debris having dead and turned cell organelle by digesting them.
(b)Lysosomes are not capable of removing the cell debris having dead and turned cell organelle by digesting them.
(c)Lysosomes are capable of removing the DNA, having died, and turned cell organelle by digesting them.
(d)None of the above

Answer 1

Hint: Lysosomes are single membrane-bound cellular organelles that possess many hydrolytic enzymes and this is the reason they are also called the suicide bags of the cell.

Complete answer:
Lysosomes also are known as scavengers of the cells because they are capable of removing the cell debris having dead and non-functioning cell organelle by digesting them. They are in the shape of spheres. The lysosomes have hydrolytic enzymes that can break down almost all kinds of biomolecules such as proteins, nucleic acids, carbohydrates, lipids, and cellular debris.

Additional Information:
-Lysosomes were discovered by the Belgian cytologist Christian René de Duve in the year 1955.
-By convention, the lysosome is the term used for animal cells.
-In the plant cells, the vacuoles do similar functions as the lysosomes.
-The lysosome is found nearly in all types of eukaryotic cells (cells with a clearly defined nucleus).
-Each lysosome is surrounded by a membrane that maintains an acidic environment within the interior via the proton pump.
-Lysosomes originate by budding off from the membrane of the trans-Golgi network, which is a region of the Golgi complex
So, the correct answer is, ’Lysosomes are capable of removing the cell debris having dead and turned cell organelle by digesting them.’

Note: The lysosomes break up larger molecules into smaller molecules. Those smaller molecules can then be used again as a building block for other large molecules. They contain more than 50 different enzymes.
