UNGRADED Ch3 Rev Sheet 3 Q # 43 - 60 2324

Meiosis is cell division that produces what type(s) of cells:

• 1. 1. gametes

• 2. 2. somatic

• 3. 3. sex

• Both 1 and 3

A gamete is

• haploid

• diploid

• fertilized egg

• produced by mitosis

Each body cell of an organism contains 50 chromosomes. The number of chromosomes in the egg cell, produced by meiosis, will be

• 50

• 25

• 100

• 12.5

The development of different organs and different tissues from a zygote includes

• mitosis and differentiation

• mitosis and gamete production

• meiosis and gamete production

• meiosis and fertilization

A diagram of the female reproductive system is shown.

Identify the structure that is the female gamete, the egg cell.

• A

• B

Meiosis I also called Meiosis Reduction because it

• reduces the chromosome number from 2n (diploid) to n (haploid).

• divides the remaining set of chromosomes in a mitosis-like process (division)

Meiosis II also called Meiosis Division because it

• reduces the chromosome number from 2n (diploid) to n (haploid).

• divides the remaining set of chromosomes in a mitosis-like process (division)
