Question

Given below is a diagram representing a stage during mitotic cell division. Study it carefully and answer the questions which follow :

(i) Is it a plant cell or an animal cell? Give a reason to support your answer.
(ii) Identify the stage shown.
(iii) Name the stage which follows the one shown here. How is that stage identified?
(iv) How will you differentiate between mitosis and meiosis on the basis of the chromosome number in the daughter cells?
(v) Draw a duplicated chromosome and label its parts.

Answer 1

(i) It is a plant cell because centrioles are not shown in the diagram.

(ii) Prophase

(iii) Metaphase. Chromosomes arrange themselves on the metaphase plate.

(iv)

Mitosis	Meiosis
Chromosome number remains the same as that of the parent cells.	Daughter cells receive only half the number of chromosomes from the parent cells.

(v) Duplicated Chromosome:
