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 Select

Check all the statements that are true for Prophase.

• Chromosomes are visible

• Centrioles are present.

• Nuclear membrane begins to break down

• Centrioles are at opposite ends of the cell.

Metaphase

• Chromosomes move to the center.

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

Multiple Select

What statements are true for metaphase? Check all that apply.

• Chromosomes line up at the center

• sister chromatids are pulled apart.

• Nuclear membrane begins to break down

• Spindle fibers attached at centromeres of chromosomes

Anaphase

• Chromatids are pulled apart.

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

Multiple Select

Check all the statements that are true for Anaphase.

• sister chromatids are pulled apart.

• spindle fibers separate chromatids.

• nuclear envelope begins to reform around each set of chromosomes

• spindle fibers disappear

Telophase

• •Nucleus begins to forms (2)

• Chromatin replaces chromosome

• Centrioles disappear

• Spindle fibers disappear

Multiple Choice

Select which statement is NOT TRUE for Telophase.

• Spindle fibers disappear

• 2 nucleus reform around chromatin

• Nuclear membrane breaks down

• Chromosomes become chromatin.
