What is the function of the body tube?
-Separates the objective and the eyepiece.
What is the function of the revolving nosepiece?
Holds the three objective lenses.
What is the function of the objective?
Provides different amounts of magnification power.
What is the objective of the stage clips?
Hold the slides in place.
What is the function of the Diaphragm?
Has different sized holes that let through different amounts of light throughout the object that is being viewed.
What is the function of the light source?
Uses to illuminate the slide or the sample form the base of the microscope.
What is the function of the eyepiece?
Contains the lens that magnifies.
What is the function of the arm?
Allows you to carry the microscope securely.
What is the function of the stage?
Supports the slide that hold up the object.
What is the function of the course adjustment knobs?
Moves the stage up or down to focus on the object to produce a clear, sharp image.
What is the function of the fine adjustment knobs?
Brings the object into sharper focus.
What is the function of the Base?
Serves as a foundation for the rest of the microscope.
What is the difference between plant and animal cells?
Plants have CELL WALLS
Plants have ONE LARGE VACUOLE
Plants have CHLOROPLASTS
What are the 4 different tissues in the human body?
C-come
E-eat
M-my
N-nachos
-Connective tissue
-Epithelial tissue
-Muscle tissue
-Nervous tissue.
What is are the differences between diffusion and osmosis?
Diffusion- Diffusion is the MOVEMENT OF MOLECULES from an area of HIGH CONCENTRATION to LOW CONCENTRATION.
Osmosis- Osmosis the DIFFUSION OF WATER through a SELECTIVELY PERMEABLE MEMBRANE.
What are the similarities between diffusion and osmosis?
Both diffusion and osmosis’s PARTICLES move from HIGH to LOW
What is the difference between unicellular and multicellular organisms?
MULTIcellular organisms are made up of TWO OR MORE CELLS
-Humans
-Whales
-UNIcellular organisms are made up of only ONE CELL
-Protozoa
-Acetabularia
