1. Teacher Notes Slides 12,13, 14,17,19,22- are not tested TEK organelles.. You can review if you want to, but they will not be tested over them.

2. Cells!

3. Cell Theory:Review all living material is made of cells cells are the basic unit of structure and function in living organisms all cells come from preexisting cells other cells all living material is made of cells cells are the basic unit of structure and function in living organisms all cells come from preexisting cells other cells

4. Every cell in your body is a living thing, and must eat (digest), breathe (respirate), and waste (excrete)! To do all these things, the cell (like you) has different parts to do each task.

5. All but 2 parts are the same in plant and animal cells, but plant cells tend to be rectangular, and animal cells vary! Plant CellAnimal Cell

6. Cell Wall (plants only!): The cell wall is rigid cellulose that gives shape, support and strength to plants.

7. Cell Membrane: The cell membrane is selectively-permeable outer layer that protects cells from the environment; allows some things to go in (food energy) and out (waste).

8. Which do you think is more permeable? A. Cell wall B. Cell membrane?

9. Nucleus: The nucleus is the control center for the cell’s activities; contain chromosomes that carry genes that are composed of DNA! This info determines your inherited traits.

11. Mom’s Traits (DNA) Dad’s Traits (DNA) Puppy’s Inherited Traits (DNA)

12. Nuclear Membrane: The nuclear membrane protects the nucleus and regulates the flow of materials in and out of the nucleus.

13. Chromatin: Chromatin contains genetic material for making chromosomes (instructions for making a duplicate cell).

14. Nucleolus: The nucleolus is where ribosomes are made, which produce proteins.

15. Cytoplasm: Cytoplasm is the jelly-fluid space in the cell outside the nucleus. It contains many Organelles. Help in the transport and movement of materials.

16. Mitochondria: The mitochondria is a rod-shaped organelle. They are the cell's power producers. Produce most of the cell’s energy needed to carry out the cell’s function. It is the “powerhouse” of the cell.

17. Endoplasmic Reticulum: The endoplasmic reticulum is a maze of passageways that carry proteins and other material from the nucleus to the organelles in the cytoplasm.

18. Ribosomes: Ribosomes are tiny organelles that make protein for the cell.

19. Golgi Bodies: Golgi bodies are organelles shaped like stacks of flattened tubes. They are the “mailroom”, receiving proteins from ribosomes to distribute around the cell.

20. Chloroplasts (plants only! Not in Animal Cells!): Chloroplasts: Food Producers! are green organelles that have chlorophyll. The function is to capture sunlight energy and convert it into (food) -chemical energy.

21. Vacuoles: Vacuoles are storage space organelles that store food, water, or waste. They connect to pores to be emptied or filled. Plant vacuoles are HUGE!

22. Lysosomes: Lysosomes are small organelles that contain chemicals that break down large food particles and old cell parts.
