Question

The largest organelle in animal cell is
A) Plastid
B) Mitochondria
C) Lysosome
D) Nucleus

Answer 1

Hint:Animal cell is a eukaryotic cell. They have a true nucleus and specialized structures called organelles which carry out different functions. Animals are all multicellular (multiple cells work together to form the whole organism).

Complete answer:
The cell organelles present in the animal cells are:-
Nucleus: it controls all the activities of cells like growth and metabolism through DNA genetic information. There is a small structure called nucleolus, that houses the RNA.
Ribosomes: They synthesize a variety of proteins that are essential to the survival of the cell. They are found floating freely in the cytoplasm of a cell or embedded within the endoplasmic reticulum.
Endoplasmic reticulum: They are of two types: rough ER and smooth ER. Rough endoplasmic reticulum are involved with protein manufacture and smooth endoplasmic reticulum serves to give essential lipids.
Golgi apparatus: It is composed of folded membranes.
Chloroplasts: It is a site for photosynthesis which contains a pigment called chlorophyll, which captures the sun's energy to transform water and carbon dioxide into glucose.
Mitochondria: The powerhouse of the cell which is oval-shaped. It serves to transform molecules known as ATP.
Nucleus is the largest organelle in the animal cell, covering upto 10% of the cell volume. Plastids are not present in animal cells.

Thus the correct answer is option ‘C’ Nucleus.

Note: In animal cells, the nucleus is located in the central region of the cell. Nucleus is one of the most important organelle present in eukaryotic cells because it serves the function of information storage, retrieval and contains genetic information.
