Answer 1

Hi hope this helps,

Chromosomes are thread-like organized structures located inside the nucleus of both animal and plant cells. Each chromosome is made of the combination of proteins and deoxyribonucleic acid (DNA).

Their functions/significance---Chromosomes basically control all the activities of a living cell. DNA present on the chromosome not only carries most of the genetic information but also controls the hereditary transference.
Chromosomes are essential for the process of cell division, are responsible for replication, division, and creation of daughter cells which contain correct sequences of DNA and proteins.
