Question

The cell component that plays a central role in cellular reproduction is -
•nucleus
•chromosome
•gene
•mitochondria​

Answer 1

Nucleus is the component which has a role in cellular reproduction.

Explaination:

The cell organelle nucleus has the genetic material, that is, the DNA in it. This is very essential for reproduction occuring in cells. In cellular reproduction, the genetic material gets transferred into the daughter cells also there occurs synthesis of various and different proteins.

Nucleus also has a role in producing the chromosomes during the division of cells. These are responsible for carrying the genetic traits from the parent cell to the cells of daughter. Thus, we can say that nucleus is that cell organelle which directly takes part in the cellular reproduction.

Answer 2

The cell component that plays a central role in cellular reproduction is •nucleus.

• The nucleus is found inside the cell and is membrane-bound in eukaryotic cells.
• The nucleus contains genetic material known as DNA which contains genes and genes contains chromosomes.
• During sexual reproduction, cell division transfers the DNA to the daughter cell.
• In meiosis, the chromosome number reduces to half.
• So, the Nucleus transfer information for the protein synthesis required for cell division that forms offspring.
