Question
Given below is a diagram representing a stage during mitotic cell division. Study it carefully and answer the questions that 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 that 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?
Solution
(i) It is a plant cell because centrosome is absent and spindle apparatus not connected to it
(ii) Prophase.
(iii) Metaphase: In this stage the chromosome lie in one plane at equator and gets attached to a spindle fibre by its centromere.
(iv) Mitosis: Same diploid number of chromosomes are present in the daughter cell.
Meiosis: Haploid number of chromosomes are present in the daughter cells.
