  1. Cell Structures, Functions and Transport

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

  3. Eukaryotic Cell Organelles and Function • Nucleus • Nickname: “The Control Center” • Function: holds the DNA • Parts: • Nucleolus: dark spot in the middle of the nucleus that helps make ribosomes

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

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

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

  7. 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:

  8. 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

  9. 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:

  10. 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

  11. 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:

  12. 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

  13. 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

  14. 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

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

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

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

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

  20. 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

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

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

  23. What Cell Look Like Animal Plant

  24. The cell is the basic unit of life. Cell walls and chloroplasts are found in plant cells only. • The cell wall is a stiff covering outside the cell membrane of a plant cell. • Chloroplast is a green structure in a plant cell where food is produced. It is green because it contains the green pigment chlorophyll.

  25. Both plant and animal cells contain:nucleus cytoplasm transport system vacuoles cell membranemitochondriachromosomes

  26. The nucleus is the control center of the cell. It controls all cell activity. The Nucleus contains chromosomes or the cell blueprints

  27. The cell membrane is the outer covering of an animal cell. It gives the cell its shape. • Most of the cells life activities take place within the cytoplasm. The mitochondrion is the powerhouse of the cell. It is a rod-shaped structure that releases energy.

  28. Respiration is the process of releasing energy in sugar that occurs in the mitochondria. Vacuoles are sac like storage spaces in both plant and animal cells. These are larger in plants than in animals. Photosynthesis only happens in plants (producers). This is where they use sunlight to make food.
