MITOSIS AND MEIOSIS

Front

What is Mitosis?

Back

Mitosis is the process of cell division that results in two 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 different gametes (sperm or eggs).

Front

What is Interphase?

Back

Interphase is the phase of the cell cycle where the cell spends most of its time (about 90%), preparing for division by growing and replicating its DNA.

Front

What happens during Prophase?

Back

During Prophase, the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the spindle apparatus begins to form.

Front

What occurs during Metaphase?

Back

During Metaphase, chromosomes line up at the cell's equatorial plane, and spindle fibers attach to the centromeres of the chromosomes.

Front

What is Cytokinesis?

Back

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

Front

What is the difference between Mitosis and Meiosis?

Back

Mitosis results in two identical cells, while Meiosis results in four genetically different cells.

Front

What is the role of spindle fibers?

Back

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

Front

What is a chromosome?

Back

A chromosome is a structure made of DNA and protein that contains genetic information.

Front

What is a gamete?

Back

A gamete is a reproductive cell (sperm or egg) that contains half the number of chromosomes of a somatic cell.
