Cell Division and Reproduction Quiz

Why is cell division beneficial to an organism?

• To increase the organism's intelligence

• To replace damaged/dead cells

• To change the organism's species

• To decrease the number of cells

What is a key reminder about mitosis mentioned in the slides and book?

• Mitosis creates cells with different DNA from each other

• Mitosis is unnecessary for skin cells

• Mitosis is how to make IDENTICAL cells

• Mitosis prevents cells from dividing

What is the purpose of meiosis?

• How to prevent meiosis

• How to make sex cells

• How to identify cells after meiosis

• How to stop genetic variety

What is one benefit of asexual vs sexual reproduction?

• One of the benefits sexual reproduction is only need one organism to keep the species from dying out. Asexual reproduction requires two healthy organism to find each other at the right time in their life to mate and produce a offspring

• One of the benefits asexual reproduction is only need one organism to keep the species from dying out. Sexual reproduction requires two healthy organism to find each other at the right time in their life to mate and produce a offspring.

• One of the benefits asexual reproduction increases genetic radiation between offspring. Sexual reproduction offspring have the same dna

• Sexual reproduction requires small cell size and simplicity. Asexual reproduction usually requires large cell sizes and complexity.

What is an aspect of meiosis that will be focused on in this unit?

• Key processes that reduce genetic variety

• Key processes that add genetic variety

• Key processes that do not affect genetics

• Key processes that eliminate the need for meiosis

What is not mentioned as a benefit of cell division?

• Asexual reproduction (cloning)

• Growth from one cell to trillions

• Increasing the lifespan of an organism

• Replacing damaged or dead cells

What is one of the advantages of asexual reproduction?

• Genetic variety

• Fast replication

• Competition for resources

• Adaptation and evolution happens quickly

What is a disadvantage of asexual reproduction?

• It requires a lot of energy

• It produces genetic variety

• It may concentrate bad genes

• It requires finding a mate

What does sexual reproduction involve?

• Joining two diploid cells to create a haploid mixture

• Joining two haploid cells to create a diploid mixture

• Joining two diploid cells to create another diploid cell

• Joining two haploid cells to create another haploid cell

What is the result of fertilization in sexual reproduction?

• A zygote with 23 chromosomes

• An embryo with 23 chromosomes

• A zygote with 46 chromosomes in 23 pairs

• An embryo with 46 chromosomes in 46 pairs
