Presentation Transcript

  1. Does it pass MR. FUDRUG test?

  2. Cell Structures, Functions and Transport

  3. Two Types of Cells Prokaryotic Eukaryotic

  4. Prokaryotic • Do not have structures surrounded by membranes • Few internal structures • One-celled organisms, Bacteria http://library.thinkquest.org/C004535/prokaryotic_cells.html

  5. Eukaryotic • Contain organelles surrounded by membranes • Most living organisms Plant Animal http://library.thinkquest.org/C004535/eukaryotic_cells.html

  6. Intro to the Animal Cell

  7. Cell Membrane • Outer membrane of cell that controls movement in and out of the cell • Double layer http://library.thinkquest.org/12413/structures.html

  8. Cytoplasm • Gel-like mixture • Surrounded by cell membrane • Contains hereditary material

  9. Figure 7-5 Plant and Animal Cells Animal Cell Section 7-2 Cytoplasm Nucleolus Nucleus Cell Membrane Go to Section:

  10. Eukaryotic Cell Organelles and Function • Nucleus • Nickname: “The Control Center” • Function: holds the DNA • Nucleolus • Spherical body in the nucleus of the cell containing RNA and produces ribosomes

  11. Figure 7-5 Plant and Animal Cells Animal Cell Section 7-2 Cytoplasm Nucleolus Ribosomes Nucleus Cell Membrane Go to Section:

  12. Eukaryotic Cell Organelles and Function • Ribosomes • Function: makes proteins • Found in all cells, prokaryotic and eukaryotic

  13. Eukaryotic Cell Organelles and Function • Endoplasmic Reticulum (ER) • Nickname: “Roads” • Function: The internal delivery system of the cell

  14. Figure 7-5 Plant and Animal Cells Animal Cell Section 7-2 Cytoplasm Nucleolus Ribosomes Nucleus Cell Membrane Smooth Endoplasmic Reticulum Rough Endoplasmic Reticulum Go to Section:

  15. Endoplasmic Reticulum • 2 Types: • Rough ER: • Rough appearance because it has ribosomes • Function: helps make proteins, that’s why it has ribosomes • Smooth ER: • NO ribosomes • Function: makes fats or lipids

  16. Figure 7-5 Plant and Animal Cells Animal Cell Section 7-2 Cytoplasm Ribosomes Nucleolus Nucleus Cell Membrane Smooth Endoplasmic Reticulum Rough Endoplasmic Reticulum Golgi Complex Go to Section:

  17. Eukaryotic Cell Organelles and Function • Golgi Complex • Nickname: The shippers • Function: packages, modifies, and transports materials to different location inside/outside of the cell • Appearance: stack of pancakes

  18. Figure 7-5 Plant and Animal Cells Animal Cell Section 7-2 Cytoplasm Nucleolus Ribosomes Nucleus Cell Membrane Smooth Endoplasmic Reticulum Rough Endoplasmic Reticulum Golgi Bodies Go to Section:

  19. Eukaryotic Cell Organelles and Function • Lysosomes: circular, but bigger than ribosomes) • Nickname: “Clean-up Crews” • Function: to break down food into particles the rest of the cell can use and to destroy old cells

  20. Figure 7-5 Plant and Animal Cells Animal Cell Section 7-2 Cytoplasm Nucleolus Ribosomes Nucleus Cell Membrane Mitochondria Smooth Endoplasmic Reticulum Rough Endoplasmic Reticulum Golgi Bodies

  21. Eukaryotic Cell Organelles and Function • Mitochondria • Nickname: “The Powerhouse” • Function: Energy formation • Breaks down food to make ATP • ATP: is the major fuel for all cell activities that require energy

  22. Eukaryotic Cell Organelles and Function • Vacuoles • Function: stores water • This is what makes lettuce crisp • When there is no water, the plant wilts

  23. Intro to the Plant Cell

  24. Figure 7-5 Plant and Animal Cells Plant Cell Section 7-2 Vacuole Cell Membrane Go to Section:

  25. Evaluate: Animal Cell Drawing • Students will draw the animal cell and label each organelle of the cell. • You can find this drawing on page 22 E in your Science book • H.w. Pg

  26. Now let’s talk about structures only found in PLANT Cells!!

  27. Figure 7-5 Plant and Animal Cells Plant Cell Section 7-2 Vacuole Chloroplasts Cell Membrane Go to Section:

  28. Eukaryotic Cell Organelles and Function • Chloroplasts • Function: traps energy from the sun to produce food for the plant cell • Green in color because of chlorophyll, which is a green pigment

  29. Chloroplasts

  30. Figure 7-5 Plant and Animal Cells Plant Cell Section 7-2 Vacuole Chloroplasts Cell Membrane Cell Wall Go to Section:

  31. Eukaryotic Cell Organelles and Function • Cell Wall • Function: provides support and protection to the cell membrane • Found outside the cell membrane in plant cells

  32. Plant Cell Cytoplasm Smooth ER Vacuole Ribosomes Chloroplasts Cell Membrane Cell Wall Nucleolus Golgi Bodies Nucleus Mitochondria Rough ER

  33. Comparing Plant and Animal Cells Plant Animal
