Analyse the events during every stage of cell cycle and notice how the following two parameters change
(i) number of chromosomes (N) per cell
(ii) amount of DNA content (C) per cell
Can there be mitosis without DNA replication in the ‘S’ phase?
Discuss with your teacher about
(i) haploid insects and lower plants where cell-division occurs.
(ii) some haploid cells in higher plants where cell-division does not occur.
What is the significance of meiosis?
