Chapter 8 - "Asexual Reproduction & Cell Division: Mitosis"

______________ is the type of reproduction that involves 1 parent, and performs exact DNA replication? During this type of reproduction, there is no fertilization. Also, cells undergo the cell division called mitosis during this type of reproduction.

• asexual reproduciton
• sexual reproduction
• binary fission
• sporulation

As we already know, bacteria reproduce very rapidly under certain environmental conditions. What is the method within which bacteria undergo asexual reproduction?

• 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.
• 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 
• Binary Fission - type of asexual reproduction where the parent organism divides equally in half reproducing identical offspring
• 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.

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?

• Starfish reproduce by budding, within which the starfish grew back and wiped out most of the oyster population.
• Starfish reproduce by binary fission, within which the starfish grew back and wiped out most of the oyster population
• Starfish reproduce by sporulation, within which the starfish grew back and wiped out most of the oyster population
• Starfish reproduce by regeneration by fragmentation, within which the starfish grew back and wiped out most of the oyster population.

During this process of asexual reproduction, the organelle called "nucleus" divides evenly, while the organelle called "cytoplasm" divides unequally? Yeast and the hydra produce by this type of asexual reproduction?

• Budding
• Binary Fission
• sporulation
• Regenertaion

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?

• regeneration - amoebas and paramecium that are split in half will regenerate, and create more identical offspring
• sporulation - as amoebas and paramecium die, they release pores that reproduce other protists under certain environmental conditions.
• binary fission - amoebas and paramecium divide by binary fission, within which the cytoplasm and the nucleus divide equally under certain environmental conditions.
• 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.

During this type of asexual reproduction,  plants produce genetically identical offshoots (clones) of themselves, which then develop into independent plants?

• Regeneration
• Vegetative Propagation

In the exploration "Bacteria Reproduction: Double Trouble", why is it important that we either freeze our food, or cook at optimum temperature extremes?

• Bacteria reproduce very quickly between the temperature ranges of 4 degrees celsius and 37 degrees celsius. If we eat meat that is under this temperature, we have the potential to have food poisoning by E.coli bacteria reproduction.
• Bacteria reproduce very quickly between the temperature ranges of 10 degrees celsius and 37 degrees celsius. If we eat meat that is under this temperature, we have the potential to have food poisoning by E.coli bacteria reproduction.
• Bacteria reproduce very quickly between the temperature ranges of 10 degrees celsius and  45 degrees celsius. If we eat meat that is under this temperature, we have the potential to have food poisoning by E.coli poisoning.
• Bacteria only reproduce under the temperatures of 4 degrees celsius , and 50 degrees celsius, within which the bacteria has potential to infect our food sources.
