  2. Azurite - Wikipedia

    en.wikipedia.org/wiki/Azurite

    Azurite has the formula Cu 3 (CO 3) 2 (OH) 2, with the copper(II) cations linked to two different anions, carbonate and hydroxide. It is one of two relatively common basic copper(II) carbonate minerals, the other being bright green malachite. Aurichalcite is a rare basic carbonate of copper and zinc. [8]

  3. Azurite (pigment) - Wikipedia

    en.wikipedia.org/wiki/Azurite_(pigment)

    Azurite is a basic compound that is coordinated with copper. [1] Azurite was popular due to its stability in various light and atmospheric conditions, making it easy to store. [1] Although azurite is permanent in oil and tempura paint, it is darkened when exposed to sulfur; this can be seen in mural paintings that use azurite.

  4. Floral morphology - Wikipedia

    en.wikipedia.org/wiki/Floral_morphology

    All spermatophytes ("seed plants") possess flowers as defined here (in a broad sense), but the internal organization of the flower is very different in the two main groups of spermatophytes: living gymnosperms and angiosperms. Gymnosperms may possess flowers that are gathered in strobili, or the flower itself may be a strobilus of fertile leaves.

  5. Biological pigment - Wikipedia

    en.wikipedia.org/wiki/Biological_pigment

    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.

  6. Branches of botany - Wikipedia

    en.wikipedia.org/wiki/Branches_of_botany

    Botany is a natural science concerned with the study of plants.The main branches of botany (also referred to as "plant science") are commonly divided into three groups: core topics, concerned with the study of the fundamental natural phenomena and processes of plant life, the classification and description of plant diversity; applied topics which study the ways in which plants may be used for ...

  7. Glossary of plant morphology - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_plant_morphology

    Non-vascular plants , with their different evolutionary background, tend to have separate terminology. Although plant morphology (the external form) is integrated with plant anatomy (the internal form), the former became the basis of the taxonomic description of plants that exists today, due to the few tools required to observe. [2] [3]

  8. Plant development - Wikipedia

    en.wikipedia.org/wiki/Plant_development

    Plants use floral form, flower, and scent to attract different insects for pollination. Certain compounds within the emitted scent appeal to particular pollinators. In Petunia hybrida, volatile benzenoids are produced to give off the floral smell. While components of the benzenoid biosynthetic pathway are known, the enzymes within the pathway ...

  9. Green pigments - Wikipedia

    en.wikipedia.org/wiki/Green_pigments

    Its name comes from the natural pigments that form a patina on copper, bronze, and brass as it ages. [5] Oneexample is the green patina that formed on the Statue of Liberty in New York Harbor. In the Middle Ages, the patina was made by attaching copper strips to a wooden block with acetic acid, then burying the sealed block in dung .
