MeiosisIB MYP Biology: Mind map

Exam questions on Meiosis

1. A biology teacher in Mumbai tells her class that human body cells each contain 46 chromosomes, but the sex cells (gametes) that parents pass on are made by a special type of cell division.
   Distinguish between the terms haploid and diploid.2 marks
2. A student in Toronto is making a revision table that compares cell division in the skin with cell division in the testes of a man. Skin cells divide to heal cuts, while cells in the testes divide to make sperm.
   Describe two differences, other than the number of cells made, between mitosis and meiosis.2 marks
3. A cell in the testes of a man contains 46 chromosomes. This cell divides by meiosis to make sperm cells, and one of the sperm later fertilises an egg cell from his partner.
   State the number of chromosomes in each sperm cell made from this cell, and explain why gametes must have this number.3 marks
