Mitosis Lesson

Mitosis

Cell Division

Phases of Mitosis

Prophase, Metaphase, Anaphase, Telophase

Multiple Choice

What is the first phase of Mitosis?

• Prophase

• Anaphase

• Telophase

• Metaphase

Multiple Choice

What is the second phase of Mitosis?

• Prophase

• Anaphase

• Telophase

• Metaphase

Multiple Choice

What is the last phase of Mitosis?

• Prophase

• Anaphase

• Telophase

• Metaphase

Multiple Choice

What is the phase that happens before telophase phase?

• Prophase

• Anaphase

• Telophase

• Metaphase

Prophase

Chromatin condenses to form visible chromosomes. The nuclear envelope disappears. More structures also appear.

Metaphase

Chromosomes line up in the middle

Anaphase

Centromeres break and sister chromatids pull apart when the spindle fibers shorten

Telophase

Chromosomes unpack to less visible chromatin and nuclear envelope. The cell begins to pull apart by pinching in the middle before it divids.

During Prophase

Chromatin condenses to form visible chromosomes. The nuclear envelope disappears. More structures also appear.

Chromosomes

Carries genetic information in the form of genes

Sister Chromatids

2 identical copies of the same chromosomes formed by DNA replication and are held together with a centromere

Multiple Choice

What happens to the nuclear envelope during prophase?

• reappears

• disappears

Multiple Choice

Which are 2 identical copies of the same chromosome that are held together with a centromere?

• sister chromatids

• chromosomes

Multiple Choice

These structures carry genetic information in the form of genes.

• sister chromatids

• chromosomes

Centrioles

Send out spindle fibers

Spindle Fibers

Attach to sister chromatids to pull apart

Centromeres

Holds 2 Sister chromatids together

Multiple Choice

Which structure attaches to sister chromatids to pull them apart?

• Centrioles

• Spindle Fibers

• Centromeres

Multiple Choice

Which structure holds 2 sister chromatids together?

• Centrioles

• Spindle Fibers

• Centromeres

Multiple Choice

Which structure sends out spindle fibers?

• Centrioles

• Spindle Fibers

• Centromeres
