38. Haploid cells are produced when diploid cells divide a. mitotically b. meiotically

Answer 1

35. Answer- e. Secondary oocyte

The Graafian follicle contains the secondary oocyte. It is further developed as ovum and released during the -recess of ovulation. The stage of corpus luteum is formed after this stage. The corpus luteum has follicular cells which secrete hormones responsible for maintenance of pregnancy. If no fertilisation occurs, it is converted further into corpus albican and is degenerated ahead.

The mature grafiaan follicle has a cell which is in stage of undergoing division, the secondary ooocyte which completes dividing after the process of fertilisation. The secondary oocyte and ovum both are haploid cells.

Therefore the correct answer is e. Secondary oocyte and all other options are incorrect.
