Cell Reproduction & Division Review

The offspring from asexually reproduced organisms are?

• Different than their parents
• Identical to parents
• Like a combination from both parents
• A different species

If two organisms reproduce sexually, then their offspring will exhibit a genetic makeup that is -

• identical to only one parent
• identical to all of its siblings
• a unique combination of traits
• the recessive traits of each parent

All of the offspring of an organism have the same genetic material, which is identical to the parent organism. From this, we can conclude that this organism -

• makes its own food
• is unicellular
• live in a marine habitat
• reproduces asexually

When comparing the offspring of sexually and asexually reproducing organisms, we would expect the genetic material (DNA) of the sexually reproducing organism to -

• contain fewer mutations
• be lesser in quantity
• be simpler overall
• show more variation

What part of our cells holds our DNA?

• cytoplasm
• cell membrane
• nucleus
• ribosomes

Which of the following is NOT an advantage of asexual reproduction?

• More efficient.
• All organisms can reproduce
• No wasted effort finding a mate.
• Population has variety to survive in a changing environment.

What type of asexual reproduction is taking place?
Fishermen work hard to catch and remove all the starfish that get into their favorite shell fishing beds and the “underwater farms” where they raise clams and oysters. In the past, they put the starfish into their boats, cut them up with knives, and then throw the pieces of starfish overboard. They thought this would kill the starfish. What they did not know was that each piece of starfish will grow into a whole new animal.

• Regeneration
• Vegetative propagation
• Budding
• Fission

Asexual reproduction like mitosis produces 

• Two offspring cells with the same genetic material as the parent cell.
• Two offspring cells with half genetic material as the parent cell.
• Four offspring cells with the same genetic material as the parent cell.
• Four offspring cells with half the genetic material as the parent cell.

Meiosis makes sperm and egg cells. In humans, sperm and egg cells each have _____ chromosomes. Therefore a fertilized human egg cell (sperm and egg cell combined) would create a cell with _____ chromosomes.

• 23, 46
• 46, 23
• 2, 4
• 50, 100

Why would it be important to replicate DNA before a cell divides in mitosis or meiosis?

• In order for the cells to have the correct amount of DNA.
• In order for the cell grow in size.
• In order for the cells to have extra DNA.
• In order for the cell to change the DNA.
