What are some processes cell have to do?

2. What makes something alive
Cellular organization
Similar life chemicals
Use energy
Grow and develop
Respond to surroundings
Reproduce.

3. 4 needs Energy Stable internal conditions/homeostasis Living Space
Water

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

5. Cell Processes The functions of cells
The chemical processes that run cells
Cell Cycle
Mitosis
Cytokinesis
Diffusion
Osmosis
Photosynthesis
Respiration

6. 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!

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

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

9. 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

10. Mitosis

11. PMAT Mom mitosis peed on the mat again!! P: Prophase M: Metaphase
A: Anaphase
T:Telophase

12. Cell Cycle 1. Interphase 2a. Mitosis: Prophase 3. Cytokinesis 2b.
Metaphase
2c. Mitosis: Anaphase
2d. Mitosis: Telophase

13. Cell Cycle 1. Interphase 2a. Mitosis: Prophase 3. Cytokinesis 2b.
Metaphase
2c. Mitosis: Anaphase
2d. Mitosis: Telophase

14. Cell Cycle

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

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

17. Cell Cycle

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

21. Interphase----In between phase
Cell grows, makes a copy of its DNA, and prepares to divide.

22. Prophase
1st step
Chromatin condenses to form chromosomes, spindle fibers form, and the nuclear membrane breaks down.

23. Metaphase
Second step
Chromosomes line up in the middle of cell.

24. Anaphase
Third step
The chromatids separate and move to opposite ends of the cell.

25. Telephase
4th step
New nuclear membranes form.

26. Cytokinesis Time to split!!
The cell membrane pinches in around the middle of the cell, and the cell divides.
