1. Interphase: Describe what happens here.
2. Prophase: Describe what happens here.
3. Metaphase: Describe what happens here.
4. Anaphase: Describe what happens here.
5. Telophase: Describe what happens here.
6. Cytokinesis: Describe what happens here.
What are three functions of cell division? Respond here.

Answer

  1. Interphase: The cell grows, duplicates its DNA, and prepares for mitosis. It consists of three phases: G1 (cell growth), S (DNA replication), and G2 (preparation for mitosis).

  2. Prophase: Chromosomes condense and become visible. The nuclear envelope begins to disintegrate, and the mitotic spindle starts to form.

  3. Metaphase: Chromosomes line up along the metaphase plate (center of the cell). Spindle fibers attach to the centromeres of the chromosomes.

  4. Anaphase: Sister chromatids are pulled apart by the spindle fibers and move toward opposite poles of the cell.

  5. Telophase: Chromatids reach the poles of the cell, and the nuclear envelope re-forms around each set of chromosomes, resulting in two nuclei.

  6. Cytokinesis: The cytoplasm divides, resulting in two separate daughter cells, each with a complete set of chromosomes.

  7. Functions of Cell Division:

    1. Growth and development of organisms.
    2. Repair and replacement of damaged or dead cells.
    3. Asexual reproduction in some organisms.
