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 CELL MEMBRANE Nucleus Cytoplasm
Animal Cell Plant Cell Photographs from:
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. Centrioles Sister chromatids Spindle fibers
Animal Cell Plant Cell Photographs from: Spindle fibers Centrioles
Chromatids (or pairs of chromosomes) attach to the spindle fibers. Centrioles Spindle fibers
Animal Cell Plant Cell Photographs from:
Chromatids (or pairs of chromosomes) separate and begin to move to opposite ends of the cell. Centrioles Spindle fibers
Animal Cell Plant Cell Photographs from:
Two new nuclei form. Chromosomes appear as chromatin (threads rather than rods). Mitosis ends. Nuclei Chromatin
Animal Cell Plant Cell Photographs from:
Cell membrane moves inward to create two daughter cells – each with its own nucleus with identical chromosomes.
