Major Organelles and their functions |
Major Organelles and their functions |
|
Cell Membrane |
The cell membrane controls.... Cell to cell recognition---carbohydrates Communication---proteins Permeability---lipid bilayer or transport proteins Nutrients (like o2)---lipid bilayer Waste (like o2)---lipid bilayer Ions, glucose, etc.---transport proteins Water Balance---lipid bilayer |
|
Nucleus |
Controls the cell Contains most of the genes that control the cell DNA is organized along with proteins forming chromatin that gives origin to chromosomes |
|
Ribosomes |
The sites where the cell assembles the proteins can be bound to the ER (endoplasmic reticulum) or be free in the cytoplasm |
|
Smooth Endoplasmic Reticulum |
Synthesis of fatty acids, phospholipids, steriods, etc. |
|
Rough Endoplasmic Reticulum |
Synthesis of protein Membrane factory
|
|
Golgi Apparatus |
Center of Manufacturing, warehousing, sorting, and shipping. (IN) Cis face- receives the vesicles from the ER (EXIT) Trans face- sends the vesicles to the rest of the cells |
|
Lysosomes |
Digest proteins, fats, polysaccharides, nucleic acids These enzymes work particularly better in an acidic environment Many cells die when the lysosomes burst at the same time (Recycling center of the cells) |
|
Vacuoles |
Food Vacuoles- fuse with lysosomes for digestion Contractile Vacuoles- pump out the excess of water Central Vacuoles- storage of organic compounds, ions, pigments, poisons, wastes, water, etc. |
|
Mitochondria |
The sites of cellular respiration, process that generates ATP by extracting energy from sugars, fats, and other fuels with the help of oxygen Have small amounts of DNA for the synthesis of their own proteins |
|
Chloroplasts |
Found in only plants Sites of photosynthesis Convert solar energy into chemical energy by absorbing sunlight and using it to fuel the synthesis of organic compounds from carbon dioxide and water Also have small amounts of DNA for the synthesis of their own proteins |

13. Nosepiece 14. Iris Diaphragm Lever 15. Iris Diaphragm Open 16. Iris Diaphragm Closed |
13. can be used to change from one objective lens, to another 14. opens and closes the light path 15. opened light path 16. closed light path |
|
Directions to view the specimen (0-4) |
0. Place one hand on the arm and one on the base while carrying it 1. Plug in the microscope 2. Turn the light on 3. Put the stage all the way down 4. Make sure its in the lowest objective lens |
|
Directions to view the specimen (5-10) |
5. Place the slide on the stage 6. Use the stage clips to put the slide in place 7. Put the stage all the way up 8. Use the coarse adjustment knob to put the specimen in focus 9. Use the fine adjustment knob to get a finer focus 10. Adjust Light (Diaphragm) |
|
Directions to view the specimen (11-12) |
11. Select another objective lens 12. Repeat 8? 9,10,11 |
|
AFTER USE |
1. Put the stage down 2. Put the lowest objective lens 3. Take the slide out 4. Turn off the light 5. Unplug it 6. Put it away |
