This organelle is like a recycling center for the cell. It breaks down old materials. It is like a vacuum cleaner that cleans up the waste in cells.
A
Ribosomes
B
Lysosomes
C
Mitochondria
D
Chloroplasts
Explanation: 

Detailed explanation-1: -Lysosomes are membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers-proteins, nucleic acids, carbohydrates, and lipids.

Detailed explanation-2: -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 and peroxisomes. These organelles are the recycling center of the cell. They digest foreign bacteria that invade the cell, rid the cell of toxic substances, and recycle worn-out cell components.

Detailed explanation-4: -In the process, the researchers found that lysosomes-the cell’s protein “recycling centers”-help govern cell division decisions.

Detailed explanation-5: -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.
