1. Anticipation Guide
Observe the pictures on the next slide and in front of you…..
Put the pictures in the correct order….or the order you think they should go
Write a short explanation for each step of the process

3. The
Cell
Cycle

4. WARM-UP
It takes Cell A 1 hour to complete its cell cycle and produce two cells. The cell cycle of cell B takes 2 hours. How many more cells would be formed from Cell A than from Cell B in 6 hours?

5. The Life of a Cell
Cell Cycle - the life cycle of a cell and how a cell lives
The cycle begins when the cell is formed and ends when the cell divides.
Must make a copy of its DNA (DEOXYRIBONUCLEIC ACID)
DNA is organized into structures called chromosomes
Each new cell will be an exact copy of the parent cell

6. Prokaryotic Cells Binary Fission-”splitting into two parts”
Results in two cells that each contain cell stuff one copy of the circle of DNA

7. Eukaryotic Cells
More complex organisms do not necessarily have more chromosomes
How many chromosomes do human cells have?
Homologous chromosomes-pairs that are made up of similar chromosomes

8. The Three Stages
Stage one-interphase-the cell grows and copies its organelles and chromosomes
Chromatids-two copies of the duplicated chromosomes
Held together in the centomere

9. Stage Two Mitosis-the process when the chromatids separate
Ensures each new cell receives a copy of each chromosome
Divided into four phases

10. Prophase
Nuclear membrane dissolves. Chromosomes condense into rod-like structures

11. Metaphase
The chromosomes line up along the equator of the cell. Homologous chromosomes pair up.

12. Anaphase
The chromotids separate and move to opposite sides of the cell

13. Telophase
The nuclear membrane forms around each set of chromosomes, and the chromosomes unwind. Mitosis is complete

14. Cytokinesis The division of cytoplasm is called cytokinesis
Plants reproduce differently
A Cell Plate-forms in the middle of the cell
Contains the materials for the new membrane and cell wall

15. A Fun Animation

16. Reproductive Cells
Meiosis-used to produce the cells animals use for sexual reproduction
Organisms produce specialized sex cells called Gametes or sex cells
Gametes contain only half the number of chromosomes found in an organism’s body cells
Two types of gametes (Sperm cells, male; Egg cells, female)
Diploid Number-total number of chromosomes present
Haploid Number-number of chromosomes present in a gamete

17. More Meiosis The Process Meiosis I-Four stages
Prophase I, Metaphase I, Anaphase I, Telophase I
Meiosis II-similar to mitosis
Chromosomes do not replicate before they begin meiosis II
