Cell Growth and Division

Cell Growth and Division:Stages of Mitosis

Prophase: First phase in mitosis. The chromatin condenses into chromosomes. The centroins separate, and a spindle begins to form. The nuclear envelope breaks down.

Metaphase: Second phase of mitosis. The chromosomes line up across the center of the cell. Each chromosome is connected to a spindle fiber at its centromere.

Telophase: Fourth phase of mitosis.The chromosomes gather at opposite ends of the cell and lose their distinct shapes. Two new nuclear envelopes will form.

As cells grow their volume increases much quicker than their surface area. When the volume gets too big for the cell to carry out necessary functions, the cell must divide into two daughter cells.

Mitosis: The part of eukaryotic cell division during which the cell nucleus divides.

Anaphase: Third phase of mitosis. The sister chromatids separate into individual chromosomes and are moved apart.

Cytokinesis: The cytoplasm pinches in half. Each daughter cell has an identical set of duplicate chromosomes.
