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 are organelles that contain digestive enzymes. They digest excess or worn out organelles, food particles, and engulfed viruses or bacteria. Lysosomes are like the stomach of the cell.

Detailed explanation-5: -In this regard, the lysosomes recycle the cell’s organic material in a process known as autophagy. Lysosomes break down cellular waste products, fats, carbohydrates, proteins, and other macromolecules into simple compounds, which are then transferred back into the cytoplasm as new cell-building materials.
