Reproduction Unit Review

What is Meiosis?

• A type of cell division that produces two identical daughter cells.

• A type of cell division that produces four genetically different gametes, which are essential for sexual reproduction.

• A process that occurs only in prokaryotic cells for reproduction.

• A method of asexual reproduction in unicellular organisms.

What is Cytokinesis?

• The process of DNA replication during cell division.

• The final stage of cell division where the cytoplasm divides, resulting in two separate daughter cells.

• The phase where chromosomes align in the center of the cell.

• The initial stage of cell division where the cell prepares for mitosis.

What is DNA Replication?

• DNA replication is the process of copying the DNA in a cell before it divides, ensuring that each new cell has the same genetic information.

• DNA replication is the process of breaking down DNA into smaller fragments for analysis.

• DNA replication is the method by which RNA is synthesized from a DNA template.

• DNA replication is the process of repairing damaged DNA strands.

What is Mitosis?

• A type of cell division that results in two genetically identical daughter cells, used for growth and repair in organisms.

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

• A form of sexual reproduction in multicellular organisms.

• A method of energy production in cells.

What is the purpose of Photosynthesis?

• To produce glucose and oxygen from carbon dioxide and water

• To absorb nutrients from the soil

• To create energy through cellular respiration

• To store energy in the form of starch

What is the difference between Sexual and Asexual Reproduction?

• Sexual reproduction involves one parent and produces genetically identical offspring.

• Asexual reproduction involves two parents and the combination of their genetic material.

• Sexual reproduction involves two parents and the combination of their genetic material, while asexual reproduction involves only one parent and produces genetically identical offspring.

• Asexual reproduction requires fertilization and results in diverse offspring.

What is Genetic Variation?

• Genetic variation refers to the differences in DNA among individuals, which can result from processes like crossing over and independent assortment during meiosis.

• Genetic variation is the process by which organisms adapt to their environment over generations.

• Genetic variation is the uniformity of genetic material within a population.

• Genetic variation occurs only in sexually reproducing organisms and is not present in asexual reproduction.

What is the significance of Crossing Over in Meiosis?

• It allows for the exchange of genetic material between homologous chromosomes, increasing genetic variation.

• It is a process that occurs only in Mitosis, ensuring identical daughter cells.

• It prevents genetic variation by maintaining the same genetic material in offspring.

• It is responsible for the replication of DNA before cell division.

What is Fertilization?

• A process where male and female gametes combine to form a zygote, leading to sexual reproduction.

• A method of asexual reproduction in plants.

• The stage of development where an embryo implants in the uterus.

• The process of cell division in organisms.

What is Asexual Reproduction?

• A mode of reproduction involving two parents producing genetically diverse offspring.

• A mode of reproduction where a single parent produces offspring that are genetically identical to itself, such as in the case of potatoes growing from tubers.

• A process where organisms reproduce through the fusion of gametes.

• A method of reproduction that occurs only in animals.
