Microscope Basics + Pond Water Organisms
This set covers some common types of microscopes, types of slides, but focuses mainly on the Compound Light Microscope - its parts and uses. Be prepared to label a diagram of the Compound Light Microscope for the quiz.
Terms in this set (39)
Allows you to view the image; also called the eyepiece
Found on the nose-piece and range from low (4x) to high power(100x).
Used to hold a slide in place on the stage.
Microscope that projects light upwards to see the specimen; also called an optical microscope
This part on the side of the microscope is used along with the base to support it when it is carried.
Coarse adjustment knob
This part moves the stage up and down to help you get the specimen into view.
Fine adjustment knob
This part moves the stage slightly to help you sharpen or "fine" tune your view of the specimen.
Attached to objective lenses and rotates around
Platform that holds the slide or specimen
The bottom part of the microscope that is used to support it when you carry it
A small plastic or glass piece that is used to cover a water drop on a slide.
Small glass plate on which specimen are placed for viewing
Way to prepare a slide using 1 drop of liquid (usually water); always uses a cover slip
Refers to the degree of magnification for a lens, such as 10X, 40X, or 100X
Power of magnification when using a 10x eyepiece and a 10x objective lens.
Power of magnification when using a 10x eyepiece and a 4x objective lens.
Power of magnification when using a 10x eyepiece and a 40x objective lens.
Regulates the light on a specimen
Microscopic, autotrophic organisms that function as producers in aquatic ecosystems
Microscopic, heterotrophic organisms in an aquatic ecosystem; includes water fleas, hydra, and nematodes
Coined the term "cell" after viewing them in his microscope made using a drop of water
Known as the father of modern microbiology; first to observe living cells, which he called animalcules
Brothers credited with the invention of the microscope
Microscope that forms an image by focusing beams of electrons onto a specimen
Allows you to see the most detail, but you only see a tiny portion of the specimen
Allows you to see a large portion of a specimen, but you do not see a lot of details
Freshwater crustacean observed in many of our pond water samples
Type of roundworm that can be found in water or soil
An aquatic invertebrate with cilia surrounding its mouth
Larval form with a siphon tube; also called a wiggler
A type of freshwater copepod; often seen with egg sacs
Nymph stage of the insect; related to damselflies
Freshwater cnidarian that uses nematocysts to paralyze its prey
Nymph stage of the insect; related to dragonflies
A protist with cilia that lives in fresh water and eats other tiny organisms for food
Nymph stage of the insect; in a different order than dragonflies and damselflies
Ostracod found in freshwater habitats
Small crustacean with seven pairs of legs; omnivores (eats both plants and animals)
Refers to a microscope or telescope with 2 or more lenses
