Biology (Day 19; Types of Reproduction)

Question 1

Sexual Reproduction

Answer 1

process of creating new individual using two parent organisms

Question 2

Asexual reproduction

Answer 2

process of creating new individual using one parent organism

Question 3

Offspring

Answer 3

a new organism that results from reproduction

Question 4

Gamete

Answer 4

Sex cell (in males: sperm; in females: eggs)

Question 5

Fertilization

Answer 5

the joining of gametes to form a new organism

Question 6

Zygote

Answer 6

a cell formed during the fusion of two gametes

Question 7

binary fission (type of asexual reproduction)

Answer 7

single parent cell doubles its DNA, then divides into two cells; usually occurs in bacteria

Question 8

Budding (type of asexual reproduction)

Answer 8

small growth on the surface of the parent breaks off, resulting in the formation of two individuals; occurs in yeast and some animals

Question 9

Fragmentation (type of asexual reproduction)

Answer 9

Organisms break into two or more fragments that develop into a new individual; this occurs in many plants, as well as some animals (like coral, sponges, and starfish)

Question 10

Parthenogenesis (type of asexual reproduction)

Answer 10

An embryo develops from an unfertilized cell; occurs in invertebrates, as well as in some fish, amphibians, and reptiles

Question 11

Sexual vs. asexual (how it occurs and the relation of offspring to parents)

Answer 11

sexual occurs: sperm fertilizes the egg; sexual relation to offspring: different from parents
asexual occurs: a single organisms makes a copy of itself; asexual relation to offspring: identical to parents
