2. A. B. C. D. G. F. E. PLANT CELL A. CYTOPLASM B. CELL MEMBRANE C. MITOCHONDRIA D. NUCLEUS E. VACUOLE F. CELL WALL G. CHLOROPLAST

3. D. B. C. A. E. ANIMAL CELL A. CYTOPLASM B. CELL MEMBRANE C. MITOCHONDRIA D. NUCLEUS E. VACUOLE

4. 1. PLANT CELL VS. ANIMAL CELL CHLOROPLASTS CELL WALL NUCLEUS VACUOLE MITOCHONDRIA CELL MEMBRANE CYTOPLASM

5. 2. ORGANELLES: STRUCTURE & FUNCTION ORGANELLEDIAGRAMPLANT/ ANIMAL/ BOTH FUNCTIONS chloroplast vacuole mitochondria plant Traps sunlight; site of photosynthesis both Stores water, food, and waste products both Stores and releases energy

6. 2. ORGANELLES: STRUCTURE & FUNCTION ORGANELLEDIAGRAM PLANT/ ANIMAL/ BOTH FUNCTIONS cell membrane cell wall cytoplasm nucleus both Surrounds and protects cell; allows materials to enter and exit the cell plant Supports and protects plant cell; gives it shape both Fills cell and surrounds other organelles both Acts as the “brain” of the cell; directs cell’s activities; contains the DNA

7. 3. C-T-O-S-O EXAMPLES CELL White blood cell, skin cell, epithelial cell, cardiac cell TISSUE Muscle tissue, brain tissue, skin tissue ORGAN Heart, lung, kidney, liver SYSTEM Circulatory system, respiratory system, digestive system ORGANISM JJ Watt, bear, dog, bobcat, horse, YOU

8. 4. What is the cell theory? The cell is the basic unit of structure (shape) and function (job) of living things. All living things are made of cells. All cells come from other cells.

9. 5. Prokaryote vs. Eukaryote No organelles No membrane nucleus Bacteria Unicellular Respond to environment Grow Reproduce Made of cells Organelles Defined nucleus Multicellular

10. 6. What is photosynthesis? The process in which plants make their own food.

11. 7. Equation for Photosynthesis

12. 8. Reactants & Products of Photosynthesis Reactants: (What reacts with the sunlight?) Carbon dioxide and water Products: (What gets produced, or made?) Glucose and oxygen

13. 9. What product gives the plant energy? NO!

14. Glucose— YES!

15. 10. What is turgor pressure? The amount of force the vacuole exerts against the cell wall Full vacuole = high turgor pressure = healthy plant Less full vacuole = low turgor pressure = wilted plant

16. 11. Turgor Pressure Lab Lab itemSalt waterPlain water Potato Celery Elodea Mushy texture Lost mass Firm texture Gained mass Became soft, floppy Remained firm Cells appeared darker green; chloroplasts were close together Cells had light areas with chloroplasts along cell wall

17. 12. Cells with different turgor pressure

18. 13. Tropism A plant’s response to a stimulus Ex: Spillane’s band plays (stimulus)... And these plants sing (response)!

19. 14. Tropisms Phototropism Geotropism Hydrotropism Thigmotropism Plant grows toward light Plant’s response to gravity (ex: roots grow down) Plants roots grow toward water Plant wraps around objects it touches

20. 15. Homeostasis Homeostasis : the process by which an organism maintains equilibrium (or balance) internally despite changes in the external environment. H o m e o s t a s i s It stays as it is.

21. Study and you’ll do fine! We believe in YOU!
