Neutral blue (rather than purplish or greenish), greenish-blue, and intense blues, available in some related Delphinium plants—particularly Delphinium grandiflorum—do not occur in this genus. Aconitum plants that have purplish-blue flowers are often inaccurately referred to as having blue flowers, even though the purple tone dominates. If ...
Chlorophyll is the primary pigment in plants; it is a chlorin that absorbs blue and red wavelengths of light while reflecting a majority of green. It is the presence and relative abundance of chlorophyll that gives plants their green color. All land plants and green algae possess two forms of this pigment: chlorophyll a and chlorophyll b.
In 1835, the German pharmacist Ludwig Clamor Marquart named a chemical compound that gives flowers a blue color, Anthokyan, in his treatise "Die Farben der Blüthen" (English: The Colors of Flowers). Food plants rich in anthocyanins include the blueberry, raspberry, black rice , and black soybean, among many others that are red, blue, purple ...
For example, having eye color is a character of an organism, while blue, brown and hazel versions of eye color are traits. The term trait is generally used in genetics , often to describe phenotypic expression of different combinations of alleles in different individual organisms within a single population , such as the famous purple vs. white ...
During the flower development we can observe change of the flower colour form purple to blue. Morning glory has just one delphinidin type anthocyanin and the composition of it does not change during the flower development, but change of the colour is caused by increase of pH in vacuole of coloured cells from 6.6 in buds to 7.7 in fully matured ...
The purple coloring is caused by hemocyanin. Spectroscopy of oxyhemocyanin shows several salient features: [21] Resonance Raman spectroscopy shows that O 2 is bound in a symmetric environment (ν(O-O) is not IR-allowed). OxyHc is EPR-silent indicating the absence of unpaired electrons; Infrared spectroscopy shows ν(O-O) of 755 cm −1
The genotype is commonly mixed up with the phenotype which describes the result of both the genetic and the environmental factors giving the observed expression (e.g. blue eyes, hair color, or various hereditary diseases). A simple example to illustrate genotype as distinct from phenotype is the flower colour in pea plants (see Gregor Mendel).
So, "a person or animal with very pale skin, white hair or fur, and pink eyes caused by a medical condition that they were born with" [13] and "a person or animal with white skin and hair and pink eyes" [14] do not include feathers, scales or cuticles of birds, fish and invertebrates, nor do they include plants. Some definitions are too broad ...
