Asexual Reproduction Mitosis
Mitosis is the process in which the nucleus divides to form two new nuclei. How does mitosis differ in plants and animals? Mrs. Camp 7th Grade Life Science 1

Cell Cycle Cell Cycle Interphase Mitosis Prophase Metaphase Anaphase
Cell Cycle Interphase Mitosis Prophase Metaphase Anaphase Telophase Cytokinesis
3
Interphase occurs before mitosis begins
Chromosomes are copied and are doubled Chromosomes appear as threadlike coils called chromatin. Each chromosome and its copy(sister chromosome) change to sister chromatids at end of this phase . CELL MEMBRANE Nucleus Cytoplasm

Prophase 1st step in Mitosis
Mitosis begins-cell begins to divide. Centrioles (or poles) appear, in animals ONLY, and begin to move to opposite ends of the cell. Spindle fibers form between the poles. Centrioles Sister chromatids Spindle fibers

Prophase Plant Cell Animal Cell Spindle fibers

Metaphase 2nd step in Mitosis
Chromatids (or pairs of chromosomes) attach to the spindle fibers. Centrioles Spindle fibers

Anaphase 3rd step in Mitosis
Chromatids (or pairs of chromosomes) separate and begin to move to opposite ends of the cell. Centrioles Spindle fibers

Telophase 4th step in Mitosis
Two new nuclei form. Spindle fibers disappear Cell Plate appears between the new nuclei in PLANT CELLS ONLY. Mitosis ends. Nuclei Nuclei Chromatin

Cytokinesis occurs after mitosis
Cell membrane moves inward to create two daughter cells – each with its own nucleus with identical chromosomes. Only in Animal Cells.
