Sexual vs Asexual Reproduction Worksheet

Question 1

What is oviparity?

Answer 1

Animals lay eggs outside of their bodies

Question 2

What is viviparity?

Answer 2

Animals give birth to live young.

Question 3

What are the advantages to genetic diversity that oviparity brings?

Answer 3

Eggs can be fertilized by male sperm, which leads to genetic diversity.

Question 4

What are the advantages of genetic diversity that viviparity brings?

Answer 4

Young animals are protected inside the mother’s body during development, which reduces the risk of predation.

Question 5

What are some disadvantages to genetic diversity that oviparity brings?

Answer 5

Eggs are vulnerable to predators and environmental conditions

Question 6

What are some disadvantages to genetic diversity that viviparity brings?

Answer 6

Young animals may be more vulnerable to disease and parasites.

Question 7

Describe pollination.

Answer 7

Pollen from male plants is transferred to female plants, which leads to fertilization and the production of seeds.

Question 8

Pollination - Advantages to genetic diversity

Answer 8

Seeds can be dispersed to new locations, which can help plants to colonize new areas.

Question 9

Pollination -Disadvantages to genetic diversity

Answer 9

Pollen can be carried by wind or insects, which can lead to cross-pollination and genetic diversity.

Question 10

Describe budding

Answer 10

A new organism develops from a bud on the parent organism.

Question 11

Advantages to genetic diversity - budding

Answer 11

Offspring are genetically identical to the parent organism, which can be helpful in stable environments.

Question 12

Budding - disadvantages to genetic diversity

Answer 12

Offspring are less adaptable to changes in the environment.

Question 13

Describe fragmentation

Answer 13

An organism breaks into two or more pieces, and each piece develops into a new organism.

Question 14

What are the advantages to genetic diversity that fragmentation brings?

Answer 14

Offspring are genetically identical to the parent organism, which can be helpful in stable environments.

Question 15

What are the disadvantages to genetic diversity that fragmentation brings?

Answer 15

Offspring are less adaptable to changes in the environment.

Question 16

What is vegetable propagation?

Answer 16

A new plant is grown from a cutting from an existing plant.

Question 17

What are the advantages to genetic diversity that vegetable propagation brings?

Answer 17

Offspring are genetically identical to the parent plant, which can be helpful in producing plants with desired traits.

Question 18

What are the disadvantages to genetic diversity that vegetable propagation brings?

Answer 18

Offspring are less adaptable to changes in the environment.

Question 19

Describe sporogenesis?

Answer 19

Spores are produced by cell division, and each spore develops into a new organism.

Question 20

What are the advantages to genetic diversity of sporogenesis?

Answer 20

Spores can be dispersed to new locations, which can help plants to colonize new areas.

Question 21

What are the disadvantages to genetic diversity of sporogenesis?

Answer 21

Offspring are genetically identical to the parent organism, which can be helpful in stable environments, but are less adaptable to changes in the environment.

Question 22

Describe parthenogenesis.

Answer 22

An egg develops into an embryo without being fertilized by a sperm cell.

Question 23

What are the advantages to genetic diversity that are brought together by parthenogenesis?

Answer 23

Offspring are genetically identical to the mother, which can be helpful in producing offspring without the need for a male.

Question 24

What are the disadvantages to genetic diversity that are brought together by parthenogenesis?

Answer 24

Offspring are less adaptable to changes in the environment.
