1.8 - Binary Fission

Question 1

Which type of organism(s) divide via binary fission?

Plants

Bacteria

Fungi

Animals

Answer 1

Bacteria

Question 2

Is binary fission a type of mitosis, a type of meiosis, or different from either?

Answer 2

Different from either

Question 3

Are bacteria eukaryotic or prokaryotic?

justify your answer

Answer 3

prokaryotic because it doesnt have a nucleus

Question 4

True or false? Bacteria are unicellular.

Justify your answer

Answer 4

True

because when they divide by binary fission they’re also reproducing each new cell as a separate organism.

Question 5

When bacteria divide by binary fission, is it an example of asexual reproduction or sexual reproduction?

Answer 5

Asexual reproduction

Question 6

Which two things must a bacterial cell do before it can divide?

Answer 6

Replicate its genetic material

Grow

Question 7

Once a bacterial cell has grown and replicated its genetic material, it is ready to divide by binary fission.

Describe the stages of this process. (3 steps)

Answer 7

The two circular strands of DNA move to opposite sides of the cell

A new cell wall forms down the middle of the cell

The two halves pull apart to form two cells

Question 8

During binary fission, are the plasmids always split equally between the two new cells?

justify your answer

Answer 8

The plasmids are randomly arranged

so there are often more plasmids in one cell that the other.

Question 9

Which three conditions do bacteria require for fast growth?

Moist

Dry

Plenty of nutrients

Cold

Warm

Answer 9

Moist

Plenty of nutrients

Warm
