Question

Centrosome is present in
A. Chromosomes
B. Nucleus
C. Cytoplasm
D. Nucleolus

Answer 1

Hint: The centrosome contains two centrioles which are present at right angles to each other. These are embedded in a mass of amorphous material that contains more than 100 different proteins in it. During the S phase of the cell cycle, it is duplicated.

Complete answer: Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is a build-up of protein and a single molecule of deoxyribonucleic acid (DNA). DNA can be said as data of the specific instructions that make each type of living creature unique which is transferred from parents to children.
-The nucleus is a membrane-bound cell organelle that contains genetic material namely DNA in eukaryotic organisms. Its main function is to maintain the integrity of the cell by facilitating transcription and replication processes. It's the largest cell organelle inside the cell taking up about a tenth of the entire cell volume but not in plant cells because in plant cells the vacuole is present.
-Cytoplasm is a thick solution that fills each cell and is enclosed by the cell membrane. It is composed of water, salts, and proteins etc. In eukaryotic cells, the cytoplasm includes all of the material inside the cell membrane and outside of the nucleus membrane. The centrosome is located in the cytoplasm, and it is usually close to the nucleus.
-The nucleolus is the distinct structure present in the nucleus of eukaryotic cells. The primary function of it is to assemble the ribosomes and alternating the transfer RNA and sensing cellular stress.
Hence, the correct answer is option C.

Note: The cytoplasm is a semi-fluid that provides a medium for the cell organelles to remain suspended. Since the cytoplasm is semi-solid or fluid-like in nature it acts as a buffer which helps in protecting the genetic material of the cell. It also helps the cell organelles from the damage which is caused due to movement and collision with other cells. Cellular respiration begins in the cytoplasm with glycolysis.
