MITOSIS
Cells need a way to divide, otherwise we would still be a single cell organism!
MITOSIS is the process of cell division, which results in two new cells formed (called DAUGHTER CELLS), identical to the original one.
Phases of Mitosis
Cell replication requires that it equally divide all of it's contents. In order for the chromosomes (the blueprint of life) to equally split into two cells, they need to first make a copy (like a photocopy) of themself. Copying of the chromosomes is done through Mitosis.
There are FIVE PHASES in mitosis.
You can remember the order with the term IP-MAT. Here's some clues to help you remember...
I = Interphase - I looks like 1, this is the first phase
P = ProPhase - note the 2 P's, the chromosomes double
M = Metaphase - starts with M, the chromosomes Meet in the Middle
A = Anaphase - starts with A, chromosomes pull Apart
T = TElophase - TE is for The End
This is the normal resting phase of a cell. It's going about its daily business.
Prophase
A cell gets the idea that it is time to divide. First, it has to get everything ready so the chromosomes need to duplicate. Remember 2p's in ProPhase means they DOUBLE!
Metaphase
Chromosomes MEET in the MIDDLE, they line up preparing to separate equally to both sides of the cell.
Anaphase: Here we go! The separation begins, and the chromosomes are pulled APART. Half of the chromosomes are pulled to one side of the cell; half go the other way. When the chromosomes get to the side of the cell, it's time to move on to telophase.
Telophase: Now cell division is getting near THE END! This is the time when the cell membrane pinches in and splits the cell into two pieces!

If the chromosomes don't duplicate before dividing the resulting cells are not the same!

Procedure
1. Carefully peel a very thin slice of onion (you should be able to see through it).
2. Place it on a pice of white paper.
3. Put a small drop of food coloring on the onion skin.
4. Look at it with a magnifying glass.
5. Draw or take a picture of what you see.
