Interphase- Cells grow prepare for cell division by copying DNA
(replication). DNA carries all information that all cells need to carry out their functions.
Divide into two new cells (Mitosis)

Asexual ReproductionMitosis
DSQ: Mitosis is the process in which the nucleus divides to form two new nuclei. How does mitosis differ in plants and animals?

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.

• 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.

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

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