Its name is derived from the Greek words χλωρός, khloros ("pale green") and φύλλον, phyllon ("leaf"). [3] Chlorophyll allows plants to absorb energy from light. Chlorophylls absorb light most strongly in the blue portion of the electromagnetic spectrum as well as the red portion. [4] Conversely, it is a poor absorber of green and ...
Chlorophyll a is the most common of the six, present in every plant that performs photosynthesis. Each pigment absorbs light more efficiently in a different part of the electromagnetic spectrum. Chlorophyll a absorbs well in the ranges of 400–450 nm and at 650–700 nm; chlorophyll b at 450–500 nm and at 600–650 nm. Xanthophyll absorbs ...
Chlorophyll a is found in all chloroplasts, as well as their cyanobacterial ancestors. Chlorophyll a is a blue-green pigment [139] partially responsible for giving most cyanobacteria and chloroplasts their color. Other forms of chlorophyll exist, such as the accessory pigments chlorophyll b, chlorophyll c, chlorophyll d, [17] and chlorophyll f.
Photosynthesis (/ ˌfoʊtəˈsɪnθəsɪs / FOH-tə-SINTH-ə-sis) [ 1 ] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism.
The antenna complex with energy transfer within the thylakoid membrane of a chloroplast. Chlorophyll a in the reaction center is the only pigment to pass boosted electrons to an acceptor (modified from 2). Absorption of light by photosynthetic pigments converts photons into chemical energy. Light energy radiating onto the chloroplast strikes ...
Chlorophyll-a concentration is a proxy for phytoplankton abundance. Darker shades of green indicate more chlorophyll and more phytoplankton, while shades of blue indicate less chlorophyll and less phytoplankton. [45] The most widely used piece of information from ocean color remote sensing is satellite-derived chlorophyll-a concentration.
