Measurement Micro PH

Biology

TermDefinition
Metric System System of measurement based on powers of ten used by scientists
Meniscus A type of lens that is convex on one side and concave on the other
Base Supports the microscope
Low power objective lens Provides magnification of 10x and is the shortest objective
High power objective lens Provides a magnification of 40x and is the longest objective
Arm Used to support the microscope when carried...holds the body tube, nose piece, and objective lenses
Nose piece Holds the objective lenses and can be turned to increase the magnification
Body tube Holds the objective lenses and the ocular lens at the proper distance
Stage Supports the specimen or slide
Stage clips Clips that hold the slide or specimen in place on the stage
Diaphragm Controls the amount of light on the slide or specimen
Course adjustment knob Used to focus under low power (moves stage up and down)
Fine adjustment knob Used to "sharpen" image under both low and high power (moves stage slightly)
Ocular lens (eyepiece) Magnifies the specimen image 10x
Total magnification Multiplying the ocular lens 10x by the objective lens
Wet mount Used to prevent specimen from falling off the slide
Coverslip This piece of glass used to cover and protect a specimen on a microscope slide
Staining Used to view specimens that are transparent (clear)
Methylene blue Type of staining
Compound light microscope Produce magnified images by focusing visible light rays, magnification is about 1000x
Basic solution (Alkaline solution) Contains lower concentrations of hydrogen ions and have PH values above 7
Acidic solution Contains higher concentrations of hydrogen ions and have PH levels below 7
Neutral solution Solutions with PH reading around 7
Buffer Weak acids or bases that can react with strong acids or bases to prevent sudden changes in PH
Field of view ("FOV") The diameter of the circle of light that you see when looking into a microscope
Slide Glass the specimen is placed on
Electron Microscope used to view dead specimens in great detail
Scanning Electron Microscope used to view great detail of the surface of a cell
Transmission Electron Microscope PH used to view interior of a specimen in great detail (Ex: organelles)

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
