Question

C. The diagrams given below show animal cells
in different stages of mitosis.
iv
o
mw
5
ii
iii
1. Using only the letters in the diagram, list the cells in
the correct sequence beginning with the cell in the
earliest stage.
2. Describe the changes happening in the genetic
material of cell in stage labelled as iii and iv.
3. Explain why cells produced by mitotic cell division
are genetically identical.​

Answer 1

Answer:

(i) Plant cell because the cell wall is present and centrioles are absent.

(ii) The above diagram shows the late prophase.

Explanation:

(i) Plant cell because the cell wall is present and centrioles are absent.

(ii) The above diagram shows the late prophase.

(iii) Metaphase follows the prophase. The chromosomes will be arranged at the equator attached to the spindle fibre.

(iv) In Mitosis: The chromosome number in the daughter cell is the same as that of the mother cell i.e., diploid mother cell gives rise to 2 diploid daughter cells.

In Meiosis: The chromosome number is halved in the daughter cells i.e., the diploid mother cell gives rise to four haploid daughter cells
