Betalains are responsible for the deep red color of beets. Anthocyanins (literally "flower blue") are water-soluble flavonoid pigments that appear red to blue, according to pH. They occur in all tissues of higher plants, providing color in leaves, plant stem, roots, flowers, and fruits, though not always in sufficient quantities to be noticeable.
Bioart is an art practice where artists work with biology, live tissues, bacteria, living organisms, and life processes. Using scientific processes and practices such as biology and life science practices, microscopy , and biotechnology (including technologies such as genetic engineering , tissue culture , and cloning ) the artworks are ...
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Cell Painting, a high-content image-based assay for morphological profiling using multiplexed fluorescent dyes. The Cell Painting assay [1] is a high-content, high-throughput imaging technique used to capture a wide array of cellular phenotypes in response to diverse perturbations. [2]
Ochre, iron oxide, was the first color of paint. [7] A favored blue pigment was derived from lapis lazuli. Pigments based on minerals and clays often bear the name of the city or region where they were originally mined. Raw sienna and burnt sienna came from Siena, Italy, while raw umber and burnt umber came from Umbria. These pigments were ...
Iridescence in soap bubbles. Iridescence (also known as goniochromism) is the phenomenon of certain surfaces that appear gradually to change colour as the angle of view or the angle of illumination changes.
Based on the stains being used, organisms with different properties will appear different colors allowing for categorization of multiple specimens. Differential staining can also be used to color different organelles within one organism which can be seen in endospore staining .
Since it was translucent, thin layers of red lac were built up or glazed over a more opaque, dark color to create a particularly deep and vivid color. Unlike vermilion or red ochre , made from minerals, red lake pigments are made by mixing organic dyes, made from insects or plants, with white chalk or alum .
