1. Horticulture Plant Cells

2. Cell Wall ONLY IN PLANT CELLS Protection and support Rigid and stiff: Made of Cellulose Permeable (allows substances to pass through)

3. Cell Membrane Protect and support Controls materials in and out 8 millionths of a mm thick (it would take 12,500 of them stacked to = the thickness of a piece of paper!!!!!!!)

4. Nucleus Control Center: regulates activities –Nuclear Membrane: controls materials in and out –Chromosomes: thin, rod-shaped, carry on traits –Nucleolus: makes ribosomes

5. Endoplasmic Reticulum -Carries proteins through the cell -System of passageways

6. Ribosomes “Protein Factory” Carried by the ER through the cell Synthesize proteins

7. Ribosomes Synthesize protein Carried by the “ER”

8. Mitochondria Supplies Energy to the cell by breaking down sugars

9. Cytoplasm Organelles exist in “jelly-like” substance

10. Vacuole Stores food, water, waste Can be up to 90% of size of cell Rigidity/turgor pressure helps plant stem remain upright

11. Lysosomes Digest food using enzymes Rare in plant cells---why??? Digest old cell parts

12. Chloroplast GREEN Trap sunlight, convert to chemical energy Contain Chlorophyll Process: Photosynthesis

13. Organelles Found Only in Plants: 1.Cell Wall 2.Chloroplast

14. Journal # 3 “Cell Drawings” 2/24/14 Observe and Draw: 1.General Plant Cell 2.Cell with chloroplasts 3.Onion skin with Iodine stain SHOW ME!!!!! Use Petri dishes as field of view!!!! Neat, lableled and colored!!!

15. *Fill Circle with Field of View *COLORS!!! 2. Chloroplasts 100x

16. Journal # 3 Plant Cells 1.Prepare a stained onion skin slide and sketch. 2.Prepare elodea “A” and sketch 3.Prepare elodea “B” and sketch 4.Sketch and Label a general Plant Cell. 5.Sketch and label a cell with chloroplasts. (4 and 5 are prepared slides)
