Solved 2014 Question Paper ICSE Class 10 Biology — Question 7
Back to all questionsQuestion 5(a)
Given below is a diagram representing a stage during mitotic cell division. Study it carefully and answer the questions which follow: [5]
(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.
(i) Plant cell.
Reason — Cell wall present and Centrioles absent.
(ii) 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 remains the same as that of the parent cell.
In Meiosis — Daughter cells receive only half the number of chromosomes from the parent cells.
(v) Below labelled diagram shows a duplicated chromosome:
