Bio SOL Review 13 - Reproduction - Mitosis, Meiosis

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is meiosis?

Back

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

Front

What is prophase in mitosis?

Back

Prophase is the first stage of mitosis where chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and spindle fibers begin to form.

Front

What is the significance of meiosis in sexual reproduction?

Back

Meiosis is crucial for sexual reproduction as it ensures that offspring have the same chromosome number as their parents by producing gametes with half the chromosome number.

Front

What happens during metaphase in mitosis?

Back

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

Front

What is anaphase in mitosis?

Back

Anaphase is the stage in mitosis where sister chromatids are pulled apart to opposite poles of the cell.

Front

What occurs during telophase in mitosis?

Back

Telophase is the final stage of mitosis where the chromosomes de-condense, the nuclear envelope re-forms around each set of chromosomes, and the cell prepares to divide.

Front

What is the role of the testis in meiosis?

Back

The testis is the male reproductive organ where meiosis occurs to produce sperm cells.

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 with half the chromosome number.

Front

What is the function of spindle fibers?

Back

Spindle fibers are structures that help separate chromosomes during cell division by attaching to the centromeres and pulling them apart.
