The process of asexual reproduction begins
after a sperm fertilizes an egg.

Skin cancer - the abnormal growth of skin cells - most often develops on skin exposed to the sun.
Cell that reproduce by asexual reproduction reproduce constantly.

Animated Mitosis Cyclehttp://www.cellsalive.com/mitosis.htm
Cellular Reproduction occurs in a series of stages, or phases:•Interphase•Prophase•Metaphase•Anaphase•Telophase & Cytokinesis
![Page 14: 1 1 Asexual Reproduction Mitosis Bell Work: Mitosis is the process in which the nucleus divides to form two new nuclei. How does mitosis differ in plants.](https://reader038.fdocuments.us/reader038/viewer/2022110404/56649e9e5503460f94b9f663/html5/thumbnails/14.jpg)
• Chromosomes are copied (# doubles)• Chromosomes appear as threadlike coils
(chromatin) at the start, but each chromosome and its copy(sister chromosome) change to sister chromatids at end of this phase

• Mitosis begins (cell begins to divide)• Centrioles (or poles) appear and begin to
move to opposite end of the cell. • Spindle fibers form between the poles.
