CELL DIVISION - Section 3 Mitosis

Cell Division 3- Mitosis

​

Mitosis

Process for growth and repair that produces 2 daughter cells identical to parent (diploid). Mitosis will divide the nucleus (the chromosomes).

Multiple Choice

Which statement is true?

• Mitosis is division of the nucleus

• Mitosis is division of the cytoplasm

Structures that aide in Mitosis

• Mitotic Spindle/Spindle fibers : extend from centromere and centrioles.

• Centrioles (centrosome): microtubules; move chromosomes.

Multiple Choice

Both spindle fibers and centrioles help organize the chromosomes during cell division.

• True

• False

Prophase

• Nucleus disappears

• Chromosomes appear.

• Centrioles appear

• Spindle fibers appear

Multiple Choice

In prophase, spindle fibers becomes visible.

• True

• False

Metaphase

• Chromosomes move to the center.

• Centrioles are responsible for placing chromosomes in the equator of the cell.

Multiple Choice

In metaphase of mitosis, the nuclear envelope begins to disappear.

• True

• False

Anaphase

• Chromatids are pulled apart.

• Centrioles will move the sister chromatids to opposite parts of the cell.

Multiple Choice

The picture to the left demonstrates the process known as anaphase.

• True

• False

Telophase

• •Nucleus begins to forms (2)

• Chromatin replaces chromosome

• Centrioles disappear

• Spindle fibers disappear

Multiple Choice

Select which one does not belong.

• Spindle fibers disappear

• 2 nucleus reform around chromatin

• Nucleus breaks down
