Q

7 types of Reproduction

A

Budding, Cloning, Binary Fission, Spore Formation, Regeneration, Cloning, Vegetative Reproduction, Parthenogenesis

20
Q

Which type of reproduction involves 2 parents?

A

Sexual

21
Q

Which type of reproduction involves regular body cells?

A

Asexual

22
Q

Which type of reproduction is slow?

A

Asexual

23
Q

Which type of reproduction is quick?

A

Sexual

24
Q

Which type of reproduction has offspring that are genetically identical to the parent?

A

Asexual

25
Q

Bacteria use this type of reproduction to reproduce

A

Binary Fission

26
Q

advantages to asexual rep.

A

does not require specialized cells, does not need alot of energy, can produce offspring quickly

27
Q

disadvantage to asexual rep.

A

limited ability to adapt

28
Q

Asexual Reproduction means…

A

Parent organism produces offspring without meiosis and fertilization

29
Q

Budding

A

parent produces a bud, bud gets detached and develops into offspring identical to the parent

30
Q

Cloning

A

performed in a lab, scientists and farmers use it to make copies of organisms/ cells w desirable traits

31
Q

Organisms that use regeneration

A

sea urchins, sea stars, planarians

32
Q

Parthenogenesis

A

Producing offspring with unfertilized eggs
