Chapter 11.1: Sexual Reproduction Requires Meiosis

Question 1

Define somatic cell

Answer 1

any of the cells of a multicellular organism except those that are destined to form gametes (germ-line cells)

Question 2

What is the diploid (2n) cell resulting from the fusion of male and female gametes (fertilization)?

Answer 2

zygote

Question 3

Define fertilization (syngamy)

Answer 3

the process by which two haploid cells (gametes) fuse to form a diploid zygote

Question 4

What is during zygote development, cells that are set aside from the somatic cells and that will eventually undergo meiosis to produce gametes?

Answer 4

germ-line cells
