Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which organelle belongs in animal cells only?
A
Chloroplast
B
Cell Wall
C
Many Small Vacuole
D
Nucleus
Explanation: 

Detailed explanation-1: -Lysosomes. Animal cells have another set of organelles not found in plant cells: lysosomes. The lysosomes are the cell’s “garbage disposal.” In plant cells, the digestive processes take place in vacuoles.

Detailed explanation-2: -The plant cell has many small vacuoles, but the animal cell has one large vacuoleThe plant cell has one large vacuole, but the animal cell has many small vacuoles.

Detailed explanation-3: -A vacuole is a membrane-bound subcellular structure involved in intracellular digestion. Instead of the large “vacuolar” organelles that are found in plants and fungi, animal cells possess lysosomes that are smaller in size and are enriched with hydrolytic enzymes similar to those found in the vacuoles.

Detailed explanation-4: -Animal cells do not have a central vacuole as seen in plant cells. However, animal cells, especially fat cells, have membrane enclosed vacuoles for storage, waste.

Detailed explanation-5: -Animal cells have one or more small vacuoles whereas plant cells have one large central vacuole that can take upto 90% of cell volume. In plant cells, the function of vacuoles is to store water and maintain turgidity of the cell.
