Cell Reproduction Review

What is a cell plate?

• A structure that forms during cytokinesis in plant cells, leading to the separation of the two daughter cells.

• A type of organelle found in animal cells that aids in cell division.

• A membrane-bound structure that stores nutrients in plant cells.

• A layer of cells that protects the outer surface of a plant.

What is internal fertilization?

• A process where fertilization occurs outside the female's body.

• A method of reproduction that involves only male organisms.

• A process where fertilization occurs inside the female's body.

• A type of fertilization that requires water for the sperm to reach the egg.

What is meiosis?

• A type of cell division that reduces the chromosome number by half, resulting in four genetically diverse gametes (sperm or eggs).

• A process of DNA replication that occurs before cell division.

• A method of asexual reproduction in unicellular organisms.

• A stage of mitosis where the cell prepares to divide.

Where does meiosis take place in males?

• In the ovaries

• In the testes

• In the prostate gland

• In the seminal vesicles

What is the haploid chromosome number?

• 46

• 23

• 22

• 24

What is the diploid chromosome number?

• 23

• 46

• 92

• 36

What is the role of the spindle apparatus during cell division?

• It helps in the formation of the nuclear envelope.

• It assists in the replication of DNA.

• It helps separate chromosomes by attaching to the centromeres and pulling them apart.

• It is responsible for the synthesis of ribosomes.

What is the role of the nuclear membrane during cell division?

• The nuclear membrane remains intact to protect the chromosomes.

• The nuclear membrane disintegrates during cell division to allow chromosomes to align and separate.

• The nuclear membrane doubles in thickness to support cell division.

• The nuclear membrane forms a barrier to prevent chromosome movement.

What is the difference between mitosis and meiosis?

• Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse gametes.

• Mitosis occurs in somatic cells, while meiosis occurs in all types of cells.

• Mitosis results in four identical daughter cells, while meiosis results in two genetically diverse gametes.

• Mitosis is a form of sexual reproduction, while meiosis is a form of asexual reproduction.

What is external fertilization?

• Fertilization that occurs inside the female's body.

• Fertilization that occurs outside the female's body, typically in water.

• A type of fertilization that requires a male and female to be in close proximity.

• Fertilization that occurs only in terrestrial environments.
