Question 1

gametogenesis

Answer 1

the production of male and female gametes - occurs in gonads

Question 2

gamete

Answer 2

haploid cells from male and female parent (sperm and egg) that combine during fertilization

Question 3

fertilization

Answer 3

the process where the sperm and egg unite creating a diploid zygote

Question 4

embryo

Answer 4

an unborn or unhatched offspring in the process of development or embryogenesis

Question 5

haploid

Answer 5

a cell that has a single set of unpaired chromosomes

Question 6

the physical movement of cells from the outside to the inside of the embryo

Question 10

Question 11

Question 11

anamniote

Answer 11

any vertebrate animal, such as a fish or amphibian, that lacks an amnion, chorion, and allantois during embryonic development

Question 12

embryogenesis

Answer 12

the differentiation of the fertilized egg into the many cell types of the body and the construction of functionally integrated organs

pronuclei

Answer 12

the nucleus found in either a sperm or egg cell during the process of fertilization

Question 13

polyspermy

Answer 13

a condition that occurs when more than one sperm fertilizes an egg

Question 14

cortical granules

Answer 14

membrane-bound and release enzymes and particles to prevent polyspermy by moving membrane away from egg
