Cell Tour

  1. 1. By Kelsey Neilson ED 205-05 Let’s Begin!
  2. 2. • Nucleus • Nuclear Envelope • Mitochondria • Ribosome • Endoplasmic Reticulum • Rough ER • Smooth ER • Golgi Apparatus • Lysosome • Cell Wall • Chloroplast • Thylakoid • Granum • Vacuole • Connection • Quiz Back Next • Concept Map • Author Page • Resources
  3. 3.  Organelle in cell that contains DNA, RNA, and Chromosomes  Contains nucleolus  Controls all cell activity  Surrounded by a double membrane known as the nuclear envelope  Found in both plant and animal cell This is a nucleus. The outer most This is an electron (orange) region with holes, is the microscope visual of nuclear envelope. The small sphere in actual nucleus the middle is the nucleolus. Home Next
  4. 4.  Outer most region of nucleus  Contains ‘pores’ for transportation of substances  Regulates what enters and leaves nucleus.  Found in both plant and animal cell For now, ignore everything else in the picture. Look closely at the nuclear envelope and the pores within it. Home Back
  5. 5.  Known as the “power house of the cell”  Contains own DNA and ribosome's  Energy producer of cell  Contains a double membrane - inner membrane: forms matrix - outer membrane: forms cristae • Found in both plant and animal cells Click 3D to see a model of the mitochondria Home Back Next
  6. 6. • Composed of proteins and RNA • Contains two subunits - large subunit - small subunit Above: 50s represents the large subunit, whereas the 30s is the small subunit of a • Site of protein synthesis ribosome. Below: Ribosome making a protein. • Found in both plant and animal cell Home Back Next
  7. 7.  Responsible for “communication” within cell  Found in both plant and animal cell  A complex of continuous membranes  Two Types: -Rough ER -Smooth ER Home Back Next
  8. 8.  Part of Endoplasmic Reticulum  Has ribosome's attached to membrane  Responsible for synthesis of some proteins Home Back
  9. 9.  Part of endoplasmic reticulum  Does not have ribosome's attached to membrane  Responsible for synthesis of lipids and carbohydrates Home Back
  10. 10.  Complex of membranes to form “sacs”  Responsible for secretion of proteins  Packages and modifies proteins/carbohydrates  Vesicles (lysosomes) bring material into the Golgi  Found in both plant and animal cell Electron Microscope vision of an actual Golgi Home Back Next
  11. 11.  Membrane bounded vesicle that carries substances from ER to Golgi  Contains digestive enzymes  Used for organelle recycling by digestion  Found in both plant and animal cell Click lysosome to see it in action! Electron microscope visual of an actual lysosome Home Back
  12. 12.  Found ONLY in plants  Responsible for protection, shape and structure  Keeps plants upright  Made of layers of proteins Left: Cell wall drawing Right: Electron Microscope of actual cell wall. Look at how thick the wall appears in the EMS picture. Home Back Next
  13. 13.  Found ONLY in plant cells  Contains a double membrane  Has own DNA and ribosome's  Site of photosynthesis  Contains thylakoids Above: Chloroplast drawing with thylakoids. Right: EMS visual of actual chloroplast. Home Back Next
  14. 14.  Found inside chloroplasts  Round disk like membranes that contain photosynthetic properties  Can be stacked to form granum Look closely at the dark areas in the EMS. These are the thylakoids Home Back
  15. 15.  Stacks of thylakoids found within the inner membrane of chloroplast  Each granum is connected by a strand of fibers to allow communication between thylakoid Home Back
  16. 16.  Membrane bounded vesicle/sac  Stores “stuff” such as water, food etc. for cell  Found in both plant and animal cells, but most commonly seen in plant cells as a Central Vacuole. Left: The large blue area is the central vacuole in a plant cell. Right: EMS visual of central vacuole Home Back Next
  17. 17.  So why do we need to know all about the cell parts? They are what comprise all living things! Without the unique function of each organelle discussed, we would not be living, nor would that cute little chick… Home Back Next
  18. 18. 1.) Which of the following organelles 3.) Which of the following are ONLY found in DO NOT have a double membrane? plant cells? - Mitochondria -Mitochondria - Lysosome -Nucleus - chloroplast - Nucleus -Lysosome -Chloroplast 2.) What organelle contains chromosomes? 4.) True or false: The smooth ER does not -Nucleus have ribosome's attached to it? -Golgi -ER -Vacuole Home Back Next
