Mitosis Flashcards
Cell division for body cells or somatic cells
Division of the nucleus also called karyokinesis
Mitosis
results in two daughter cells that are genetically identical to each other and to the parental cell from which they came.
Mitosis
Chromatin in nucleus condenses to form visible chromosomes
Spindle fibers forms from the centrioles
Nucleolus and nuclear membrane will disappear.
Prophase
Chromosomes, attached to the spindle fibers, move to the center of the cell
Chromosomes are now lined up at the
equator
Metaphase
Sister chromatids are pulled apart to opposite poles of the cell by spindle fibers
Anaphase
Two daughter cell form
Chromosomes reappear as chromatin
Nucleolus and nuclear membrane reappears
Telophase
Division of cytoplasm
To form two new cell
Cytokinesis
The number of cells increases by mitosis enabling organisms to grow from a single cell to a complex multicellular organism.
Development and growth
Cells are constantly lost and replaced by new ones in the body.
Cell replacement
Some organisms use mitosis to replace body parts
Replacement of damaged plant or animal tissue (regeneration)
Some organisms such as the hydra use mitosis to produce genetically identical offspring. The process is known as budding
Asexual reproduction
4 stages of mitosis
Prophase, Metaphase, Anaphase and Telophase
Division of the nucleus also called
Karyokinesis
