Round packets that contain chemicals that break down substances
A
Lysosomes
B
Golgi bodies
C
nucleus
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: -Answer and Explanation: The cellular organelle that packages enzymes and forms lysosomes is known as the Golgi Apparatus.

Detailed explanation-3: -Lysosomes are considered as the important organelle that breaks down large molecules into small molecules so that they can be reutilized. These organelles are not formed by the process of packaging in the endoplasmic reticulum.

Detailed explanation-4: -Lysosomes act as recycling centers within cells. They use digestive enzymes to break down toxic substances, digest bacteria that invade the cell, and recycle worn-out cell components.

Detailed explanation-5: -Lysosome Action Since lysosomes are little digestion machines, they go to work when the cell absorbs or eats some food. Once the material is inside the cell, the lysosomes attach and release their enzymes. The enzymes break down complex molecules that can include complex sugars and proteins.
