[[File:Immersionsvorteil.jpg|thumb|"Principle of immersion microscopy. Path of rays with immersion medium (yellow) (left half) and without (right half). Rays (black) coming from the object (red) at a certain angle and going through the coverslip (orange, as the slide at the bottom) can enter the objective (dark blue) only when immersion is used."(https://en.wikipedia.org/wiki/Oil_immersion)]] | |||

=== Microscopy with Oil Immersion=== | |||
"In light microscopy, oil immersion is a technique used to increase the resolving power of a microscope. This is achieved by immersing both the objective lens and the specimen in a transparent oil of high refractive index, thereby increasing the numerical aperture of the objective lens. Immersion oils are transparent oils that have specific optical and viscosity characteristics necessary for use in microscopy."(https://en.wikipedia.org/wiki/Oil_immersion) | |||

“The BioGame ‘Blocksworld repopulated!’ gives you the opportunity to plunge into a labyrinth populated by microorganisms that you can interact with. Instead of encountering programmed entities in ‘Blocksworld repopulated!’ you are playing with living Euglenas, uni-cellular organisms that are part plants and part animals.” | “The BioGame ‘Blocksworld repopulated!’ gives you the opportunity to plunge into a labyrinth populated by microorganisms that you can interact with.

A protist is any eukaryotic organism that is not an animal, plant or fungus. The protists are unicellular or unicellular-colonial and form no tissues. | A protist is any eukaryotic organism that is not an animal, plant or fungus.

"Amoebe is an organism which has the ability to alter its shape, primarily by extending and retracting pseudopods."(wikipedia). | |||
"An Amoeba is unable to form its food from simple substances, but it requires ready-made organic substances for food; such a mode of nutrition in which solid organic particles are ingested is called zoo trophic or holozoic."(http://www.biologydiscussion.com/invertebrate-zoology/protozoa/amoeba-proteus-habitat-structure-and-metabolism/28183) | |||
"A. proteus can be called 'immortal', as it does not die due to natural death on its own, due to binary fission. .. A. proteus reproduces asexually and so it simply copies its genetic information into the second cell." (https://davidwangblog.wordpress.com/life-cycle-and-reproduction/) | |||

"Amoebae move and feed by using pseudopods, which are bulges of cytoplasm formed by the coordinated action of actin microfilaments pushing out the plasma membrane that surrounds the cell. Typically, an amoeba moves by extending a pseudopod, attaching it to the substrate and filling it with cytosol, then releasing its rear portion from attachment to the substrate, which results in the organism being propelled forward."(wikipedia) | |||
=== | "A pseudopod or pseudopodium (plural: pseudopods or pseudopodia) (from the Greek word ψευδοποδός, ψευδός "false" + ποδός "foot") is a temporary cytoplasm-filled projection of a eukaryotic cell membrane or a unicellular protist. Pseudopods may be used for motility, or for ingesting nutrients or other particulate matter."(wikipedia) | ||
