Question 1

What is binary fission?

Answer 1

• A single parent cell replicates its genetic material and divides into two equal parts
• Occurs in unicellular organisms only

Question 2

What are some examples of binary fission?

Answer 2

Amoebas, Streptococcus bacteria, Alexandrium acatenalla (marine algae)

Question 3

What is budding?

Answer 3

Question 8

What is an example of vegetative reproduction?

Answer 8

Tulips, daffodils, strawberry runners, potato sprouts,

Question 9

What is spore formation?

Answer 9

• Form single-celled spores
• Spores are reproductive cells that grow into new individuals by mitosis
• Rely on water and wind to carry spores

What are some examples of spore formation?

Answer 10
