Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which organelle functions to digest and breakdown old organelles and/or removal of pathogens?
A
lysosomes
B
mitochondria
C
centrioles
D
chromatin
Explanation: 

Detailed explanation-1: -Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself.

Detailed explanation-2: -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-3: -Lysosomes are membrane-bound organelles found in every eukaryotic cell. They are widely known as terminal catabolic stations that rid cells of waste products and scavenge metabolic building blocks that sustain essential biosynthetic reactions during starvation.

Detailed explanation-4: -The lysosome is an organelle that contains digestive enzymes and acts as the organelle-recycling facility of an animal cell. It breaks down old and unnecessary structures so their molecules can be reused. Lysosomes are part of the endomembrane system, and some vesicles that leave the Golgi are bound for the lysosome.

Detailed explanation-5: -Lysosomes destroy microorganisms with the help of hydrolytic enzymes present in them. For e.g. a macrophage engulfs the microorganism through phagocytosis after which fuses with lysosomes, in which the pathogen is destroyed by hydrolytic enzymes. The key function of the lysosomes is the digestion & removal of waste.
