When the stalk is dried out, it is crushed to extract its green juice (the liquid is green because of chlorophyll in the plant).
The chlorophyll bodies of green cells arrange themselves similarly.
The explanation is, of course, that chlorophyll is soluble in alcohol.
The chlorophyll bodies work away on these minerals, and make them into foods.
It is after the chlorophyll is withdrawn that the layer of cork is formed.
Iron enters into the composition of chlorophyll, and to it is due the brown color of dead leaves.
"You will find that the streets actually are filled with chlorophyll," the vine said.
The spectrum of chlorophyll, the green colouring matter of plants, shows two very strong absorption bands in the red.
The yeast plant and its allies are saprophytes and form no chlorophyll.
The colour then of the chlorophyll is due to the absence of certain colours from the spectrum of white light.
chlorophyll chlo·ro·phyll or chlo·ro·phyl (klôr'ə-fĭl)
Any of a group of related green pigments found in photosynthetic cells that converts light energy into ATP and other forms of energy needed for biochemical processes; it is found in green plants, brown and red algae, and certain aerobic and anaerobic bacteria.
Any of several green pigments found in photosynthetic organisms, such as plants, algae, and cyanobacteria. At its molecular core, chlorophyll has a porphyrin structure but contains a magnesium atom at its center and a long carbon side chain. Chlorophyll absorbs red and blue wavelengths of light, but reflects green. When it absorbs light energy, a chlorophyll molecule enters a higher energy state in which it easily gives up an electron to the first available electron-accepting molecule nearby. This electron moves through a chain of acceptors and is ultimately used in the synthesis of ATP, which provides chemical energy for plant metabolism. Plants rely on two forms of chlorophyll, chlorophyll a (C66H72MgN4O5) and chlorophyll b (C66H70MgN4O6), which have slightly different light absorbing properties. All plants, algae, and cyanobacteria have chlorophyll a, since only this compound can pass an electron to acceptors in oxygen-producing photosynthetic reactions. Chlorophyll b absorbs light energy that is then transferred to chlorophyll a. Several protist groups such as brown algae and diatoms lack chlorophyll b but have another pigment, chlorophyll c, instead. Other closely related pigments are used by various bacteria in photosynthetic reactions that do not produce oxygen. See more at photosynthesis.
Our Living Language : From its name, one might think that chlorophyll has chlorine in it, but it doesn't. The chloro- of chlorophyll comes from the Greek word for "green"; chlorophyll in fact is the chemical compound that gives green plants their characteristic color. The name of the chemical element chlorine comes from the same root as the prefix chloro-, and is so called because it is a greenish-colored gas.
