1 1 Asexual Reproduction Mitosis DSQ: Mitosis is the process in which the nucleus divides to form two new nuclei. How does mitosis differ in plants and animals? Mrs. Camp 7 th Grade Life Science
How do little elephants grow up to be BIG elephants?
The process of asexual reproduction (cell life cycle) 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 Cell Life Cycle Cell Life Cycle Stages Interphase M1- Prophase M2- Metaphase M3- Anaphase M4- Telophase Cytokinesis
Chromosomes and ALL organelles are copied. Chromosomes appear as threadlike coils ( chromatin ) at the start, but are almost invisible with a light microscope. CELL MEMBRANE Nucleus Cytoplasm
Animal Cell Plant Cell Photographs from:
Mitosis begins. Chromosomes visible. Centrioles (or poles) appear and begin to move to opposite end of the cell. (Not in Plants) Spindle fibers form between the poles. Centrioles Sister chromatids Spindle fibers
