Chapter 9 - Asexual/Sexual Reproduction

Question 1

What is the definition of asexual reproduction?

Answer 1

It involves only one parent, identical to parent and single organism can produce a large amount.

Question 2

What are the advantages to asexual reproduction?

Answer 2

• if parent does well, then the offspring will do well

- only needs one parent so they can produce frequently and have a large population

Question 3

What are the disadvantages to asexual reproduction?

Answer 3

• if parent doesn’t do well, then the offspring will not

- all offspring will be affected if parent has a disease

Question 4

What is Binary Fision?

Answer 4

Binary Fision is a form of asexual reproduction. It is when the parent undergoes cell division, it’s on a smaller scale (molecular) and its necessary for rapid reproduction or growth.

Question 5

What is Budding?

Answer 5

Budding is a form of asexual reproduction. It is when a small growth begins on the parent, the bud undergoes cell division and breaks free from parent at the right size. (single cell)

Question 6

What is Vegetable Reproduction?

Answer 6

Vegetable Reproduction is a form of asexual reproduction. It is a blanket term used to describe three similar forms of asexual reproduction. “Runners”, “Tubers” and “Shooters”.

Question 7

What is a “Runner”?

Answer 7

A “Runner” is a form of asexual or more specifically vegetable reproduction. It is when a long slender stem runs across the soil, with “nodes” that the roots stem off of into the soil to create plants like strawberries.

Question 8

What are the disadvantages to asexual reproduction?

Answer 8

• if parent doesn’t do well, then the offspring will not

- all offspring will be affected if parent has a disease

Question 9

What is a “Tuber”?

Answer 9

A “Tuber” is a form of asexual or more specifically vegetable reproduction. It is when a tube shoots from the base (or “mother”) plant into the soil, potato “eyes” are an example of this.

Question 10

What is a “Shooter”?

Answer 10

A “Shooter” is a form of asexual or more specifically vegetable reproduction. It is when a plant sends out shoots from the base of it’s trunk to turn into new plants.

Question 11

What is the definition of sexual reproduction?

Answer 11

It involves two parents, and the offspring are unidentical to sibling or the parents.

Question 12

What are the advantages to sexual reproduction?

Answer 12

• allows for genetic variation for species survival
• adaptation
• “survival of the fittest” passed on genetics “survival genes”

Question 13

What are the disadvantages to sexual reproduction?

Answer 13

• need to find a mate
• fewer offspring than asexual
• slower until gamates

Question 14

What are the three main types of sexual reproduction?

Answer 14

Conjugation, hermaphrodites and separate sexes.

Question 15

What are the disadvantages to asexual reproduction?

Answer 15

• if parent doesn’t do well, then the offspring will not

- all offspring will be affected if parent has a disease

Question 16

What is Binary Fision?

Answer 16

Binary Fision is a form of asexual reproduction. It is when the parent undergoes cell division, it’s on a smaller scale (molecular) and its necessary for rapid reproduction or growth.

Question 17

What is a “Shooter”?

Answer 17

A “Shooter” is a form of asexual or more specifically vegetable reproduction. It is when a plant sends out shoots from the base of it’s trunk to turn into new plants.

Question 18

What is Fragmentation?

Answer 18

Fragmentation is a form of asexual reproduction. It is when a small part of a organism breaks off and forms a new worm. An example: worms.

Question 19

What is Spore?

Answer 19

Spore is a form of asexual reproduction. It is when an organism forms large numbers of spores that grow and develop on their own. They are identical to the host.

Question 20

What is Spore?

Answer 20

Spore is a form of asexual reproduction. It is when an organism forms large numbers of spores that grow and develop on their own. They are identical to the host.

Question 21

What are the five main types of asexual reproduction?

Answer 21

Binary fision, budding, veg repro, fragmentation and spore.

Question 22

What is the definition of sexual reproduction?

Answer 22

It involves two parents and the offspring is nonidentical to its parents and siblings.

Question 23

What is conjugation?

Answer 23

Conjugation is a form of sexual reproduction. It is when two unicellular transfer or exchange some genetic material.

Question 24

What is a hermaphrodite?

Answer 24

A hermaphrodite is a form of sexual reproduction. It a organism that produces male and female sex cells and can mate with any other of the same species.

Question 25

In a flower what are the male gametes and gonads.

Answer 25

Male = stamen, its made of filament and it produces pollen. The pollen contains male gametes.

Question 26

In a flower what are the female gametes and gonads.

Answer 26

Female = pistol, the eggs are located in the ovary (center bulb-like thing).

Question 27

How does a flower reproduce?

Answer 27

Pollen travels down the stigma to ovary to fertilize the eggs.

Question 28

What are all the parts of a flower pistol?

Answer 28

Stigma, style and the ovary.

Question 29

What are all the parts of a flower stemen?

Answer 29

Anther and filament

Question 30

What are separate sexes?

Answer 30

There exactly what you think they are, two separate organisms with separate sexes. Male = sperm, female = eggs.

Question 31

What is the difference between external fertilization and internal fertilization?

Answer 31

What do you think? In external the female releases eggs, and the sperm is released over top OUTSIDE. Guess where internal fertilization happens? INSIDE THE FEMALE.

Question 32

What are the three types of sexual reproduction?

Answer 32

Conjugation, hermaphrodites and separate sexes.
