Cell Reproduction

Hailey is comparing and contrasting various forms of cellular reproduction, and she focuses her research on meiosis. Meiosis is important for sexual reproduction because it gives sex cells (gametes) what unique feature?

• They contain only half the genetic material of the parent.

• They are able to exist outside of the organism.

• They are smaller than all other cells in the body.

• They have a very short life span.

Sexual and asexual reproduction allow for transfer of genetic material to offspring. Which of the following is true regarding how mitosis differs from meiosis?

• Mitosis is cell reproduction for animals; meiosis is cell reproduction for plants.

• Mitosis produces genetically identical cells; meiosis does not.

• Meiosis is a form of asexual reproduction; mitosis is a form of sexual reproduction.

• Meiosis produces genetically identical cells; mitosis does not.

Mrs. Rodriguez shows her seventh-grade class a video on cellular division of a germ cell dividing by meiosis and a human zygote dividing by mitosis. Which of the following might be included in this video as the best description of the difference in the results of mitosis and meiosis?

• Mitosis results in daughter cells with a complete set of genes; meiosis results in daughter cells with half the genes.

• Mitosis results in four or more daughter cells; meiosis results in only two daughter cells.

• Mitosis produces results in only a few seconds; meiosis produces results that require several hours.

• Mitosis results in daughter cells with a cell membrane; meiosis results in daughter cells with a cell wall.

Reproduction is a process by which an organism produces offspring, or young, and passes on its traits or characteristics. Mitosis is important for asexual reproduction because it gives cells what unique feature?

• Opportunity for increased genetic variability

• Decrease in the chance of mutation

• Ability to reproduce at a faster rate

• Production of genetically identical daughter cells

Mitosis is responsible for creating what cells in organisms?

• Only sex cells, known as gametes

• Only skin and hair cells

• All cells, except sex cells

• All cells in sexually reproducing plants

Traits of organisms are a direct result of two factors: the genetic material present in previous generations and the type of reproduction, sexual or asexual. Which of the following is true of cellular division through sexual reproduction and asexual reproduction?

• Meiosis is cellular division for asexual and sexual reproduction.

• Asexual reproduction requires mitosis for cellular division.

• Mitosis is cellular division for asexual and sexual reproduction.

• Sexual reproduction requires mitosis for cellular division.

Mitosis and budding are similar because both have what characteristic?

• Both processes are components of sexual reproduction

• The offspring produced by both are genetically diverse

• In both, the genetic material comes from a single parent.

• Both processes are more common in animals than in plants.

Which of the following bestdescribes how the types of cell reproduction relate to major groups of organisms?

• Meiosis only occurs in plants and fungi.

• Mitosis occurs only in animals with backbones.

• Meiosis only occurs in organisms that reproduce sexually.Mitosis occurs only in organisms that have cell walls.

• Mitosis occurs only in organisms that have cell walls.

Which of the following is considered a process that is part of sexual reproduction?

• A sperm fertilizes an egg

• A bacterium makes a copy of itself

• A mushroom produces spores

• A jellyfish releases a bud
