Answer 1

Answer:

$\huge\mathsf\red{Answer:-}$

Explanation:

✳️ Centromere :- the region of a chromosome to which the microtubules of the spindle attach, via the kinetochore, during cell division.

✳️ Centrosome :- an organelle near the nucleus of a cell which contains the centrioles (in animal cells) and from which the spindle fibres develop in cell division.

✳️ Chromosome :- threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.

✳️Cell cycle :-A cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division.

Hope it helps!!!
