  • Interesting fact: Mushrooms have no chlorophyll so they don't need sunshine to grow and thrive. Some of the earliest commercial mushroom farms were set up in caves in France during the reign of King Louis XIV (1638-1715).
    • Chlorophyll any of a group of green pigments found in photosynthetic organisms. Chlorophyll a and chlorophyll b are found in higher plants and green algae; chlorophyll c is found in certain types of marine algae. Chemically, it has a porphyrin ring with a magnesium ion bound to the four central nitrogens, and has a phytyl side chain. It is essential for photosynthesis in most plants. Chlorophyll a has formula C55H72N4O5Mg.
    • Chlorophyll (Bot) Literally, leaf green; a green granular matter formed in the cells of the leaves (and other parts exposed to light) of plants, to which they owe their green color, and through which all ordinary assimilation of plant food takes place. Similar chlorophyll granules have been found in the tissues of the lower animals.

Masked in the chlorophyll's intenser green,
The feast of crimson was already there,
These yellows blazed unseen.

An even more challenging test is chlorophyll, a molecule which is of fundamental importance for life on Earth since it is responsible for the photosynthetic process.
Turbo charging time-dependent density-functional theory with Lanczos chains
Historically the interpretation of the visible spectrum of chlorophyll relies on the 4-orbital Gouterman model of porphyrins in which only the two highest occupied molecular orbitals and the two lowest unoccupied molecular orbitals are considered.
