As we already know, animal like protists (the amoeba and paramecium) reproduce by asexual reproduction. Which of the following is an example of how the amoeba and paramecium reproduce using asexual reproduction?
a)
regeneration - amoebas and paramecium that are split in half will regenerate, and create more identical offspring
b)
sporulation - as amoebas and paramecium die, they release pores that reproduce other protists under certain environmental conditions.
c)
binary fission - amoebas and paramecium divide by binary fission, within which the cytoplasm and the nucleus divide equally under certain environmental conditions.
d)
budding - amoebas and paramecium reproduce by budding, within which the cytoplasm divides unequally, and the nucleus divides equally. The amoeba or paramecium can either create a colony, or split into two different protists.
2.
Which of the following is/are advantages of asexual reproduction?
a)
It allows the organisms to crowd out the other organisms that reproduce more slowly. As we have seen, bacteria can reproduce very rapidly in a short time!
b)
Asexual reproduction allows the organism to better fight off diseases, unlike organisms that reproduce sexually. Asexual reproduction allows for greater diversity, in turn, asexual reproducers have a greater life expectancy.
c)
Most asexual reproductive organisms live in ideal conditions, which allows them to reproduce rapidly.
d)
both b and c are correct
3.
As we already know, bacteria reproduce very rapidly under certain environmental conditions. What is the method within which bacteria undergo asexual reproduction?
a)
Budding - asexual reproduction in which a new organism develops as an outgrowth of the parent. The new organism, called the bud, is a tiny duplicate of the parent organism. In budding, the nucleus divides equally and the cytoplasm divides unequally.
b)
Regeneration by Fragmentation - type of asexual reproduction where the organism fragments a piece of itself off. In turn, the fragment reproduces an identical creature. Examples are flatworms and starfish
c)
Binary Fission - type of asexual reproduction where the parent organism divides equally in half reproducing identical offspring
d)
Sporulation - cells that contain a nucleus and a small amount of cytoplasm. Spores are surrounded by tough protective coats that enable them to survive unfavorable conditions, such as extreme heat or cold, for long periods of time. When environmental conditions become favorable, each spore can develop and produce by releasing spores.
4.
During the late 1800's, oyster fishermen were having a problem with starfish eating most of the oyster population. As a result, the fishermen "cut apart" the starfish. Why would this be a "bad" idea?
a)
Starfish reproduce by budding, within which the starfish grew back and wiped out most of the oyster population.
b)
Starfish reproduce by binary fission, within which the starfish grew back and wiped out most of the oyster population
c)
Starfish reproduce by sporulation, within which the starfish grew back and wiped out most of the oyster population
d)
Starfish reproduce by regeneration by fragmentation, within which the starfish grew back and wiped out most of the oyster population.

9.
As we already know, onions reproduce asexually. How does an onion reproduce asexually?
a)
The parent onion sends out tendrils which can take root and grow into new organisms. This type of asexual reproduction can be called a runner.
b)
The onion has eyes, within which the eyes of an onion create a new organism by sprouting out from the original tuber.
c)
The parent onion is a bulb, within which the onion parent bulbs create lateral buds or shoots, which can grow into new bulbs and grow into separate organisms.
d)
Onions reproduce by splitting them in half, and planting them into the soil. This is an asexual process known as fragmentation by regeneration.
10.
Which of the following is/are disadvantages of asexual reproduction?
a)
It allows the organisms to crowd out the other organisms that reproduce more slowly. As we have seen, bacteria can reproduce very rapidly in a short time!
b)
Most organisms that reproduce by asexual reproduction do not live in ideal conditions. Most of the reproduction is kept in check by limited resources, predators, and their own waste.
c)
Organisms that tend to reproduce by asexual reproduction are not able to fend off diseases, unlike organisms that are able to reproduce sexually. Asexual reproduction involves 1 parent and one source of DNA, within which asexual organisms are not able to fend off diseases
d)
Both ideas are correct, within which most organisms that reproduce by asexual reproduction do not live in ideal conditions, and diseases can be passed on by the identical parent offspring.
