Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What organelle digests food for the cell and recycles old organelles?
A
Lysosomes
B
Vacuole
C
Nucleous
D
ribsomes
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: -Proteins aren’t the only type of cellular waste. Cells also have to recycle compartments called organelles when they become old and worn out. For this task, they rely on an organelle called the lysosome, which works like a cellular stomach.

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: -Lysosomes breakdown/digest macromolecules (carbohydrates, lipids, proteins, and nucleic acids), repair cell membranes, and respond against foreign substances such as bacteria, viruses and other antigens. Lysosomes contain enzymes that break down the macromolecules and foreign invaders.

Detailed explanation-5: -Lysosomes assist in the intracellular digestion of worn-out cellular organelles and materials taken into the cell by endocytosis.
