The _____________ _____________ is a series of steps that cells go through to ____________ and ___________. It can be split into three distinctive processes: ________________, mitosis and ___________________. The first process can be broken down into three distinctive sub-phases. During ____________ and ____________ the cell is carrying on normal cell functions like growing and producing proteins. However, during _____________ the cell’s _____________ is replicated. The cell cycle has _______________ along the way to make sure cells are not reproducing incorrect versions of themselves. In rare occurrences damaged or abnormal cells can get copied which can lead to ______________ or ________________.

Title: Mitosis
EQ:
What are the stages of mitosis and why are they important to the growth of organisms?

Slide4Today’s Standard:
[BIO.5A]
The student will
describe the stages of the cell cycle
, including mitosis and theimportance of the cell cycle to the growth of organisms
Slide5CELL DIVISION
:
process where a cell divides into
TWO identical
daughter cells

purpose is to make an exact copy

CYTOKINESIS
Today we will cover the l
ast two
parts
of the cell cycle
:
Mitosis
(
M-phase
) and Cytokinesis
Slide7MITOSIS (M phase)
: division of the cell’s nucleus
*
it is divided into FOUR PHASES aka: PMAT
Slide8What are the four phases of Mitosis?
Umm, what the heck is a PMAT?
Slide9Before we move on…
The next few slides will be discussing chromosomes. As a student you’ll need to remember that Chromosomes are tightly coiled DNA. DNA is located in the nucleus.
Slide10Onion Root Tip
Mitosis only occurs while cells are dividing.
Cells perform mitosis for growth and repair.
The tip of a root is growing almost constantly, therefore when we zoom in on an onion root tip we should see mitosis going on.
Slide11Interphase
: Nucleus
is
still visibleMost cells are in this phase (includes G1, S, G2)
*if you can see a nucleus…it’s interphase
Slide12Prophase
: Nucleus disappears,
Individual
c
hromosomes
condense and are visible.
*looks like noodles
Slide13Slide14The centrioles are two tiny structures located in the cytoplasm
that help organize the spindle.The spindle is a fanlike microtubule structure that helps separate the chromosomes.
Slide15Metaphase
:
Spindle fibers attach and line up chromosomes at the equator (center) of the cell
*M means “middle”
Slide16ANAPHASE: the centromeres joining the sister chromatids split;
chromosomes move away to opposite sides of the cell, near the poles of the spindle.*A means “away”
Slide17TELOPHASE: chromosomes are
on opposite sides; nuclear membranes reappear to form two new nuclei(nuclei = more than 1 nucleus)*T means two
Slide18CYTOKINESIS
:
-division of the cytoplasm; two identical cells are produced
-final stage of the cell cycle

Slide22Slide23The cell cycle is an on-going process.
The pictures below are “snapshots” of cells at various stages of mitosis.
So, you may see a cell “on it’s way” to metaphase or anaphase. They will not stay in any phase permanently.
The cells will continue through the process and
repeat until they die.
