Q2 of 33 Page 18

Match the events given in column A with the phase in mitotic cell division in Column B























Column 'A'



Column 'B'



(a) Chromosomes get arranged in a horizontal the plane at the equator.



Anaphase



(b) Daughter chromosomes move to the opposite poles of a spindle.



Prophase



(c) Chromosomes become visible as fine long threads.



Telophase



(d) Chromosomes lose their distinctiveness and gradually become transformed into a chromatin network.



Metaphase


(a) - Metaphase; (b) – Anaphase; (c) – Prophase; (d) – Telophase

Mitosis occurs in somatic cells. It is an equational division in which two diploid daughter cells are formed. It is divided into four phases- Prophase, metaphase, anaphase, and telophase.
