Cell Cycle & Mitosis

Cell Cycle & Mitosis

What type of cell does mitosis? Eukaryote,

Prokaryote, or Both

only eukaryotic cells do mitosis

Cell Cycle & Mitosis

What happens when a unicellular

eukaryote completes mitosis?

In unicellular organisms Mitosis

makes a new organism

Cell Cycle & Mitosis

Does a new organism form

through mitosis of a eukaryotic multicellular organism?

No, a multicellular eukaryotic

organism does not make a new

organism through mitosis.

Cell Cycle & Mitosis

Then for what does a eukaryotic multicellular organism use

mitosis?

Cell Cycle & Mitosis

Instead a multicellular eukaryotic

organism uses mitosis for repair,

growth, and development

.

Cell Cycle & Mitosis

Do bacteria use mitosis to make new organisms?

Bacteria do not use mitosis at all because bacteria

have only one chromosome

attached to a cell membrane and use fission to create more

bacteria.

Interphasenot really mitosis

premitosis•Interphase (before mitosis but often mistakenly put as part of mitosis)•G1 + S + G2 = Cell grows, makes

more cytoplasm and organelles duplicate, copies DNA, and gets ready to divide

Mitosis starts with Prophase

•Remember Please Make Another Taco

•Prophase, Metaphase, Anaphase, Telophase

Prophase•Chromosomes pack up•Centrioles go to opposite sides of cell•Spindle fibers reach from centrioles to

chromosomes•Nuclear membrane falls apart•Remember packed up the centrioles

moved and spin a nuclear fall apart like a little military event

Metaphase•During late prophase or into

metaphase chromatids move to center are of cell

•remember•At metaphase the chromatids met

in the middle chromatids are aligned

Anaphase

•Chromatids move apart, toward opposite poles

•remember•Sister Anna moved to the opposite

side

Telophase• Chromosomes are at opposite parts of the

cell•nuclear membranes reforms around

each set of chromosomes•chromosomes uncoil •spindle fibers fall apart•Remember telo like telecommunications so

wires uncoil, fiber optics, at the end of any war you must rebuild so we started with membrane falling apart now it rebuilds

Mitosis ends here and cytokinesis is

separate

Cyto indicating a cell as in cytoplasmKinesis as in movement after a

stimuliTherefore

Cytokinesis is…….

Cytokinesis•Cytokinesis = splitting of the

cytoplasm•Not an actual phase of mitosis.•The division of cytoplasm after

separation of the chromosomes•In plant cells, a new cell wall forms to

divide the two daughter cells (CELL PLATE)
