STUDY CELL DIAGRAMS AND MICROSCOPE DIAGRAMS!!
Vocabulary:
Unicellular: made up of only one cell (Example: Bacteria)
Multi-cellular: made up of more than one cell (Examples: mushrooms, dogs, plants)
Prokaryotic: Cells do NOT contain a nucleus
Eukaryotic: Cells do contain a nucleus
Cell Organization:
cells  tissues  organs  organ systems  organisms
Cell Discovery: Robert Hooke discovered cells in cork in 1665.
Cell Theory: Cells are the smallest living thing, Every living thing is made of cells, Cells divide to form
new cells
Cell Organelles and Functions
Vacuole
Stores water and other materials
Endoplasmic reticulum
Transports materials through out the cell
Golgi complex
Packages materials to be sent out of the cell
Chloroplast
Absorbs sunlight in plants to make food
Nucleus
Controls all activities in the cell
Cytoplasm
Jelly-like fluid that organelles are found in
Ribosome
Make proteins from amino acids
Cell membrane
Allows materials in and out of the cell
Cell wall
Protects and supports plant cells
Lysosome
Removes wastes from animal cells
Mitochondria
Turns food into energy in the cell
Magnification: Multiple eyepiece magnification by objective magnification. 10x times 100x = 1000x
Orientation: Objects in the eyepiece appear upside down and backwards from the object on the slide.
The size of the field of view decreases as you go from low power to high power.
Determining field of view: Count the spaces between the lines. Remember 1 mm = 1000 μm
Determining object size: Divide the field of view by the number of cells (3000 μm / 10 cells = 300 μm)
Eyepiece: Where you put your eye to see the specimen
Body tube: Supports the eyepiece
Coarse adjustment knob: Makes large adjustments to focus. Moves the stage. No HIGH power!
Fine adjustment knob: Makes small adjustments to the focus.
Stage: Where you place the slide
Stage clips: KEEPS THE SLIDE IN PLACE
Diaphragm: Allows different amounts of light onto the stage
Arm: Connects the eyepiece to the base
Base: Supports the microscope
Light: Allows light onto the stage to see the specimen
Nosepiece: Holds and rotates the objectives
Objective: Magnifies the specimen
