Which organelle helps digest unwanted materials?
A
lysosome
B
ribosome
C
Rough ER
D
vacuole
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: -When food is eaten or absorbed by the cell, the lysosome releases its enzymes to break down complex molecules including sugars and proteins into usable energy needed by the cell to survive. If no food is provided, the lysosome’s enzymes digest other organelles within the cell in order to obtain the necessary nutrients.

Detailed explanation-4: -Lysosomes have powerful enzymes and acids to digest and recycle cell materials.

Detailed explanation-5: -The main function of lysosomes is the digestion of internal (non-functional cell organelles) and external (food, bacteria, leukocytes, debris) material. The processed material is either released to the cytoplasm, secreted, or stored in lysosomes.
