Cell Theory
All cells come from cells Cells are basic unit of structure and
function All living things are composed of cells.

Cell Theory
All cells come from other cells.
New Skin cells come from skin cells
All special cells originally come from stem cells that came from egg cells that came from our parent cells.
Babies are made from cells from parents!

Cell cycle
The process of cells making new cells. split a cell in two. Important process
Allows growth Development Reproduction

Discussion
What needs to happen for a cell to split in two.
Does it become two half cells? What does each cell need?

Cell Cycle
The process of a cell copying itself and then splitting is called the cell cycle.
Three parts Interphase: Growing getting ready for
mitosis Mitosis : copying the nucleus Cytokinesis : Splitting in half

Cell CycleCell grows, makes a copy of its DNA, and prepares to divide.
Chromatin condenses to form chromosomes, spindle fibers form, and the nuclear membrane breaks down.
Chromosomes line up in the middle of cell.
The chromatids separate and move to opposite ends of the cell.
New nuclear membranes form.
The cell membrane pinches in around the middle of the cell, and the cell divides.

Interphase----In between phase
Cell grows, makes a copy of its DNA, and prepares to divide.
![Page 22: Cell Processes](https://reader035.vdocuments.us/reader035/viewer/2022070403/568139f9550346895da1bdb1/html5/thumbnails/22.jpg)
Prophase
1st step
Chromatin condenses to form chromosomes, spindle fibers form, and the nuclear membrane breaks down.
![Page 23: Cell Processes](https://reader035.vdocuments.us/reader035/viewer/2022070403/568139f9550346895da1bdb1/html5/thumbnails/23.jpg)
Metaphase
Second step
Chromosomes line up in the middle of cell.
![Page 24: Cell Processes](https://reader035.vdocuments.us/reader035/viewer/2022070403/568139f9550346895da1bdb1/html5/thumbnails/24.jpg)
Anaphase
Third step
The chromatids separate and move to opposite ends of the cell.
![Page 25: Cell Processes](https://reader035.vdocuments.us/reader035/viewer/2022070403/568139f9550346895da1bdb1/html5/thumbnails/25.jpg)
Telephase
4th step
New nuclear membranes form.
![Page 26: Cell Processes](https://reader035.vdocuments.us/reader035/viewer/2022070403/568139f9550346895da1bdb1/html5/thumbnails/26.jpg)
Cytokinesis
Time to split!!
The cell membrane pinches in around the middle of the cell, and the cell divides.
