Foxfire in the fungus Panellus stipticus Blue ocean glow caused by myriad tiny organisms, such as Noctiluca. Noctiluca scintillans, a bioluminescent dinoflagellate. Bioluminescence is the production of light by living organisms. This list of bioluminescent organisms is organized by the environment, covering terrestrial, marine, and microorganisms.
The host organisms provide these bacteria [clarification needed] a safe home and sufficient nutrition. In exchange, the hosts use the light produced by the bacteria for camouflage, prey and/or mate attraction. Bioluminescent bacteria have evolved symbiotic relationships with other organisms in which both participants benefit each other equally. [2]
Stentor coeruleus, used in molecular biology (its genome has been sequenced), [5] and is studied as a model of single-cell regeneration.; Dictyostelium discoideum, used in molecular biology and genetics (its genome has been sequenced), and is studied as an example of cell communication, differentiation, and programmed cell death.
Acetabularia is a genus of green algae in the family Polyphysaceae. [4] Typically found in subtropical waters, Acetabularia is a single-celled organism, but gigantic in size and complex in form, making it an excellent model organism for studying cell biology. [5]
Therefore, the organism is an excellent model for studying cell differentiation. D. discoideum exhibiting chemotaxis through aggregation. Chemotaxis is defined as a passage of an organism toward or away from a chemical stimulus along a chemical concentration gradient. Certain organisms demonstrate chemotaxis when they move toward a supply of ...
A wheeled buffalo figurine—probably a children's toy—from Magna Graecia in archaic Greece [1]. Several organisms are capable of rolling locomotion. However, true wheels and propellers—despite their utility in human vehicles—do not play a significant role in the movement of living things (with the exception of certain flagella, which work like corkscrews).
[5] [10] From 1910 to 1927, Thomas Hunt Morgan's work with the fruit fly Drosophila melanogaster identified chromosomes as the vector of inheritance for genes, [11] [12] and Eric Kandel wrote that Morgan's discoveries "helped transform biology into an experimental science". [13] Research in model organisms led to further medical advances, such ...
Xenophyophorea / ˌ z ɛ n ə ˌ f aɪ ə ˈ f oʊ r iː ə / is a clade of foraminiferans.Xenophyophores are multinucleate unicellular organisms found on the ocean floor throughout the world's oceans, at depths of 500 to 10,600 metres (1,600 to 34,800 ft).
