Mitosis Chapter 10

Depending on cell type… Mitosis can take a few minutes or a few days Muscle cells Nerve cells Skin cells Digestive Tract cells

Mitosis can take a few minutes or a few days

Muscle cells

Nerve cells

Skin cells

Digestive Tract cells

Prophase 50-60% of time Chromosomes become visible Centrioles develop in cytoplasm near nuclear envelope Centrioles separate and migrate to opposite ends of nuc. Env. Centrosome Region where Centrioles are found Organize the “spindle” Fan like microtubule structure that helps separate chromosomes Plants do NOT have Centrioles

50-60% of time

Chromosomes become visible

Centrioles develop in cytoplasm near nuclear envelope

Centrioles separate and migrate to opposite ends of nuc. Env.

Centrosome

Region where Centrioles are found

Organize the “spindle”

Fan like microtubule structure that helps separate chromosomes

Plants do NOT have Centrioles

 

 

End of prophase Chromosomes coil together tightly Nucleolus disappears Nuclear envelope breaks down

Chromosomes coil together tightly

Nucleolus disappears

Nuclear envelope breaks down

Metaphase Few minutes Chromosomes line up in middle (M in metaphase  MIDDLE) Microtubules connect centromere of each chromosome to the 2 poles of spindle

Few minutes

Chromosomes line up in middle (M in metaphase  MIDDLE)

Microtubules connect centromere of each chromosome to the 2 poles of spindle

 

 

 

Anaphase Centromeres joining sister chromatids separate and become individual chromosomes They are dragged by fibers to opposite poles Ends when chromosomes stop moving

Centromeres joining sister chromatids separate and become individual chromosomes

They are dragged by fibers to opposite poles

Ends when chromosomes stop moving

 

 

 

Telophase Opposite of prophase Condensed chromosomes disperse into tangle of material Nuclear envelope reforms Spindle breaks apart Nucleolus becomes visible At the end  2 identical nuclei in one cell

Opposite of prophase

Condensed chromosomes disperse into tangle of material

Nuclear envelope reforms

Spindle breaks apart

Nucleolus becomes visible

At the end  2 identical nuclei in one cell

 

 

 

Cytokinesis Happens at the same time as Telophase Division of cytoplasm Animal Cells Cell membrane drawn inward until it pinches off and forms 2 id daughter cells Plant Cells Cell plate forms between nuclei Cell Plate develops into separate membrane Cell wall appears

Happens at the same time as Telophase

Division of cytoplasm

Animal Cells

Cell membrane drawn inward until it pinches off and forms 2 id daughter cells

Plant Cells

Cell plate forms between nuclei

Cell Plate develops into separate membrane

Cell wall appears
