Fill in the blanks

(a) Mitosis occurs in our .................... cells.

(b) Mitosis produces two daughter cells whereas meiosis produces ....................daughter cells.

(c) Meiosis occurs only in .................... cells.

(d) Modern humans have 46 chromosomes. Their sperms and eggs will have ................... chromosomes each.

(e) During the pairing of chromosomes in meiosis, the.................... chromosomes come to lie side by side.

(f) The ................ (s) are surrounded by radiating rays and termed as aster.

(a) Somatic

Mitosis occurs in somatic cells. It is an equational division in which two diploid daughter cells are formed.)

(b) Four

In the meiosis division, a diploid cell undergoes two successive divisions to give rise to four haploid cells.

(c) Reproductive

Meiosis occurs in male and female reproductive cells i.e., ovary and testis.

(d) 23

The gametes (sperm and eggs) are produced as a result of meiosis hence they have a haploid number of chromosomes.

(e) Homologous

The pairing of homologous chromosomes is called synapsis.

(f) Centriole

Aster is a star like structure present at the opposite poles of a dividing cell. Aster rays arise from the centriole and radiate out.
