T.G.I.F.

Today in class…

We finished up our mitosis lab with the onion cells and turned in pages UP44-51. We talked more about mitosis and what it is.

Mitosis

*Have 4 stages

Prophase-

-Chromosomes condense

-Nuclear membrane disappears

-Spindle fibers form as centrioles move toward the poles.

Metaphase-

- Chromosomes line up along the cell center

- Chromosomes attach to spindle fibers at the centromers

Anaphase-

-Sister chromatids separate and move toward the poles.

Telephone-

-Last step of mitosis

-Individual chromosomes gather at poles

-Nuclear membrane reforms

cytokinesis

-Cell pinches in half

-Two cells form

*Animal cell-cleavage furrows

Here’s a video on mitosis…

Homework

-Read pages 43-44 in text book

-Read section 10.3 and read UP 52B-52D and use the flow map note taking skill about the “causes/effects of unregulated cell cycle.”(Go on moodle or look in your packet for the outline of the flow map)

Reminders!!!

- Create a student account by Tuesday

- Cancer paper due October 25

- Cell test on Wednesday!!!

Cell test

*Look over labs and make sure you understand them!!

-Enzyme pre lab

-Mitosis lab

-Plasmolysis lab

-Cell structures and function lab

* Reread the sections in the book about cells

*Look over cell quiz
