General Biology 1: Mitosis and Meiosis Quiz

Mitosis and meiosis are both types of cell division, but they have different outcomes. Mitosis results in two daughter cells that are genetically identical to the parent cell. This process is used for growth and repair. Meiosis results in four daughter cells that are genetically different from the parent cell. This process is used for sexual reproduction. The stages of mitosis are prophase, metaphase, anaphase, and telophase. The stages of meiosis are prophase I, metaphase I, anaphase I, telophase I, prophase II, metaphase II, anaphase II, and telophase II.

A type of cell division resulting in two identical daughter cells with the same number and kind of chromosomes as the parent cell.

A special type of cell division creating four daughter cells with half the chromosome number of the parent cell.

The series of events a cell goes through as it grows and divides.

The part of the cell cycle where the cell grows, replicates its DNA, and prepares for cell division.

First stage of mitosis and meiosis; chromosomes condense and the nuclear envelope breaks down.

Following prophase; nuclear envelope completely breaks down, spindle fibers attach to chromosomes.

Chromosomes align in the middle of the cell.

Sister chromatids separate and move to opposite poles of the cell.

Chromosomes reach the poles, nuclear envelopes reform, and the cell begins to divide.

Division of the cytoplasm; creating two separate daughter cells.

Diploid; containing two sets of chromosomes.

Haploid; containing one set of chromosomes.

Exchange of genetic material between homologous chromosomes during meiosis.

A thread-like structure of DNA carrying genetic information.

Identical copies of a chromosome.

Chromosome pairs (one from each parent) that have similar structures & genes.

Section of DNA that codes for a specific trait

Process of making an identical copy of DNA

Protein structures that help in separating chromosomes during cell division.

The region where two sister chromatids are joined.

A protein structure on the centromere that attaches to the spindle fibers.

Reproductive cells (sperm or egg) that are haploid.

Imaginary line across the center of a cell where chromosomes align during metaphase.

First division in meiosis; reducing the chromosome number to half.

Second division in meiosis; separating sister chromatids to make four haploid cells.
