- Cell Discovery
- Anton van Leeuwenhoek
-
- Early 1600s 3. Saw tiny organisms in pond water
- Robert Hooke
-
- 1665 4. Saw tiny chambers in cork tissue 5. Termed the tiny chambers cells
6.
- Different Microscopes
- Different microscopes reveal different aspects of this Green Algae
7.
- Major Types of Cells
- Prokaryotes
-
- Bacteria
- Eukaryotes
-
- Plants 8. Animals 9. Fungi 10. Protists
11.
- Prokaryotes vs. Eukaryotes
- Smaller, relatively simple 12. NO Nucleus, but has DNA 13. Ie. Bacteria 14. Include cytoplasm, ribosomes, & genetic material
- All contain Nuclei 15. Most contain organelles 16. Unicellular or multicellular organisms 17. Animal, Fungi, Protists, & Plant Cells
18.

22.
- Cell Membrane
- Thin, Flexible Barrier 23. Protection and Support 24. Skin of the cell 25. Boundary
-
- Allows interactions w/surroundings
26. Front and back views of a 3D model of the Golgi region in an insulin-secreting, mammalian cell 27. 28.
- Cell Wall
- Stronger layer outside of cell membrane 29. Support & Protect 30. Permeable to Water, Oxygen, CO 2 , & others 31. Found in Plants, Algae, Fungi & Prokaryotes
32.
- Cytoskeleton (Microtubules & Microfilaments)
- Help the cell maintain its shape. 33. Assists with movement 34. Serve as tracks along which organelles move 35. Form cilia & flagella
36.
- Endoplasmic Reticulum (ER)
- Ribosomes
- Made of RNA & Proteins 37. Assembled in the nucleolus 38. Makes proteins
- Internal membrane system 39. Assembles components (lipids) of the cell membrane (Smooth ER) 40. Modifies proteins (Rough ER)
41.
- Golgi Apparatus
- Completes, stores, and moves products made in the ER (ie. Proteins)
- Package finished material for shipment to final destinations
42. 43.
- Lysosome
- Stores enzymes to digests lipids, carbohydrates, & proteins 44. Breaks down old cell parts
45.
- Vacuole
- Primarily found in Plants 46. Sac-like structure 47. Stores water and products 48. Tiny vacuoles (called vesicles) are found in animal cells
49.
- Chloroplast
- Contains Chlorophyll 50. Uses sunlight, carbon dioxide, & water to make food
-
- Photosynthesis
- Chloroplast- site of photosynthesis Found commonly in plants.
51.
- two outer membranes
- Thylakoid membrane, a much-folded single flattened compartment inside the stroma
- Fig. 4-20, p.65
- stroma (semifluid interior)
- central vacuole
- chloroplast in the cytoplasm of a plant cell
52.
- Mitochondria
- Converts food molecules into ATP (the powerhouse) 53. Found in PLANTS & animals 54. Contain their own DNA (former prokaryotes???) 55. Humans inherit from their mom.
