True-False Questions
11. Mitosis in animal cells is exactly
the same as mitosis in plant cells.
12. In prophase, the chromatids are
pulled to the poles of the cell.
13. Spermatogenesis forms 4 daughter
cells called sperm.
14. Meiosis makes gametes in all
organisms.
15. Oogenesis is the production of 1
egg and 3 polar bodies.
Short Answer Questions
16. Sketch a diagram showing mitosis
of a parent cell with 4
chromosomes.
17. Sketch a diagram showing meiosis
of a parent cell with 4
chromosomes.
18. The formation of a new human
follows these processes – meiosis,
fertilisation, mitosis. Explain.
19. Where in your body are meiosis
and mitosis occurring right now?

18. Adults humans produce haploid
gametes (sperm and ova) be
meiosis in the testes and ovaries.
After sexual intercourse,
fertilisation is the joining of one
sperm and one ovum to form the
diploid zygote. The zygote then
divides by mitosis to grow into a
new human about 40 weeks later.
19. Meiosis may be occurring with the
production of gametes in gonads.
Mitosis is occurring in all body
organs as new cells are made. The
only exception to the prolific
regrowth of new cells is the
nervous system.
20. Crossing over and recombination
may occur during meiosis when
parts of homologous chromosomes
break and rejoin, so that
combinations of genes in the
offspring were not present in the
parents.
