The Cell Cycle, Mitosis and Meiosis

All living things are made up of at least one or more cells. Because they contain cells they must be able to reproduce to continue living. The Cell Cycle illustrates how cells go through various stages to ultimately reproduce or divide to make new cells. Mitosis is a process through which cells divide to form new cells. Meiosis occurs in almost the same way Mitosis does except for a few different steps.

Cells Alive: The Cell Cycle

The cell cycle is made up of several stages including:

G1:Resting Phase- actually this is deceiving, instead the cell is actually carrying out its normal everyday functions.

S: Synthesis- during this phase the DNA is replicating or making copies of itself.

G2: Growth and Development- During this phase, the cell is preparing to enter mitosis.

 

MITOSIS: The process of cellular replication or cellular division.

Interphase: (The Cell Cycle)

Prophase:

Metaphase:

Anaphase:

Telophase:

Cytokinesis:
