Warm Up1. How does an asexual organism reproduce?2. Name the three reasons that a cell divides.3. What is cellular division?4. Why is it important that we have cell

division?

Agenda

Science Fair Projects are REALLY late…◦Calls home start this weekend.

Notebook Check on FRIDAY

Quiz

Mitosis

What is mitosis?Mitosis is the process that divides the cell’s nucleus into two, each with a complete set of genetic material from the parent cell.

4 phases

Vocabulary Recap

Nucleus: Organelle that is the “command center” of the cell and contains all the genetic information

◦Surrounded by a Nuclear Membrane

Chromosome: threadlike structure that carries the genes (aka DNA)

◦In the NUCLEUS

Remember the tool?

Mitosis is used for….

CD is Cell Division

G is GrowthR is RepairR is Reproduction

1. Prophase

Chromosomes condense and the nuclear membrane disappears.

Early Prophase Late Prophase

2. Metaphase

Chromosomes line up in the center of the cell.

3. Anaphase

Chromosomes separate.

Early AnaphaseLate Anaphase

4. Telophase

New nuclei form containing exact copies of the original cell’s DNA.

Cytokinesis

The cell pinches in the middle and divides into two daughter cells.

What do you think?

Mitosis is:

◦Asexual Reproduction?

OR

◦Sexual Reproduction?

Hint: ◦Asexual--one cell makes two identical offspring◦Sexual--two cells make genetically different offspring

Mitosis Foldable

A student will be bringing around science textbooks. Turn to page C83.

You will also receive a foldable.

Label the top flap, “STAGES of MITOSIS”

Mitosis Foldables

You will create five flaps to representPMAT….C

Use a pencil and two different colored markers from the bins.

When you are done with the markers, please put them back in my box.

Turn your foldables into me! I will return them.
