How do little elephants grow up to
be BIG elephants?
The
process is
Mitosis
the process in which the
nucleus divides to form two
new nuclei.
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.
There are 6 stages to Mitosis:
• Interphase
• Prophase
• Metaphase
• Anaphase
• Telophase & Cytokinesis
•
•
Chromosomes are copied (# doubles)
Chromosomes appear as threadlike coils
(chromatin) at the start, but later 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.

Two new nuclei form.
Chromosomes appear as chromatin (threads
rather than rods).

Cell membrane moves inward to create two
daughter cells – each with its own nucleus
with identical chromosomes.
