2.3 Cell Division

2.3 Cell Division

Mr. Tudor

Learning Objective

• I can summarize the functions of cell division

• I can identify the events that take place during the three stages of the cell cycle.

Cell Division Allow...

• grow

• repair damaged structures

• reproduce

Cell Cycle

During the cell cycle the, a cell growns, prepares for division into two new cells, which are called daughter cells

Interphase

The cell grows, copies DNA, and prepares for Division. Please read G1 (Gap 1)-S (Synthesis)-G2 (Gap 2)

Multiple Choice

What does not happen during interphase

• cell grows

• cell makes a copy of its DNA

• The cell prepared to divide

• The cell divides

Multiple Choice

Cell division allow organisms to do everything except...

• repair

• evolve

• grow

• reproduce

Mitosis

• The division of the nucleus

• Occurs in 4 steps

Cytokinesis

The last step, be sure to look for the cleavage furrow!

Please Remember!

• PMAT = Mitosis

• IPAMATC = Entire Cell cycle

Multiple Choice

The first step of mitosis, where chromosomes become visible and nuclear membrane dissolves.

• Prophase

• Metaphase

• Anaphase

• Telophaes

Multiple Choice

The phase of mitosis where by spindle fibers pull chromosomes to opposite ends of the cell

• prophase

• metaphase

• anaphase

• telophase

Multiple Choice

Chromosomes line up in the middle of the cell

• prophase

• metaphase

• anaphase

• telophase

Multiple Choice

Which is not a phase of mitosis?

• prophase

• metaphase

• anaphase

• cytokinesis
