Mitosis and Meiosis Review

Front

What is the main purpose of mitosis?

Back

The main purpose of mitosis is to produce two genetically identical daughter cells for growth, repair, and asexual reproduction.

Front

What is the main purpose of meiosis?

Back

The main purpose of meiosis is to produce gametes (sperm and eggs) with half the number of chromosomes, promoting genetic diversity through sexual reproduction.

Front

Define asexual reproduction.

Back

Asexual reproduction is a mode of reproduction that involves a single parent and produces offspring that are genetically identical to the parent.

Front

Define sexual reproduction.

Back

Sexual reproduction is a mode of reproduction that involves the fusion of gametes from two parents, resulting in genetically diverse offspring.

Front

What are somatic cells?

Back

Somatic cells are any cells in the body that are not gametes; they undergo mitosis for growth and repair.

Front

What are germline cells?

Back

Germline cells are the reproductive cells that give rise to gametes through meiosis.

Front

What happens during prophase of mitosis?

Back

During prophase, chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and spindle fibers begin to form.

Front

What happens during metaphase of mitosis?

Back

During metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres.

Front

What happens during anaphase of mitosis?

Back

During anaphase, sister chromatids are pulled apart toward opposite poles of the cell.

Front

What is the difference between mitosis and meiosis?

Back

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