Chlorophylls - Role of Pigments in Photosynthesis

For photosynthesis to occur, plants need: · Light energy from the sun · Chlorophyll to absorb light energy · Carbon dioxide from the atmosphere and from respiration in plant cells · Water which is absorbed by the roots and transported to the leaves by the xylem tubes....

Chlorophylls function in photosynthesis

Photosynthisis is the way in which light and carbon-dioxide is used by a plant to produce energy in the form of starch.

The actual chemical equation which takes place is the reaction between carbon dioxide and water, powered by sunlight, to produce and a waste product, oxygen. The glucose sugar is either directly used as an energy source by the plant for metabolism or growth, or is polymerised to form , so it can be stored until needed. The waste oxygen is excreted into the atmosphere, where it is made use of by plants and animals for respiration.


are composedof a hydrocarbon tail bound to an active site that contains Mg2+. The several different pigment types absorb light at different wavelengths. Chlorophyll a (plants and algae) absorb light wavelengths between 425 and660 nM (violet and red), while bacteriochlorophyll in purple sulfur bacteriaabsorb wavelengths between 350 and 880 nm (ultraviolet and infrared). Pigments are embedded in layers of membranes called (layers of the cell membrane in bacteria, foldings of the inner membraneof eukaryotic chloroplasts). The fluid interior of the chloroplastis called the and contains enzymesfor the synthesis reactions of photosynthesis. The light reactionsresponsible for ATP generation, called and , occur in the thylakoids.

Photosynthesis is the process by which green-plants use sunlight, carbon dioxide, water & chlorophyll to produce their own food source.

A) sunlight concentration B) temperature C) chlorophyll concentration D) carbon dioxide availability Effects of the variables and there concentrations: The amount of sunlight will decide the rate of photosynthesis as there will be a an increased rate of photosynthesis due to the increased availability of photons of light....

Chlorophylls and bacteriochlorophylls serve – noncovalently bound to specific proteins – as principal energy‐transforming cofactors in photosynthesis.

Chlorophyll - Simple English Wikipedia, the free …

Photosynthesis depends upon the absorption of light by pigments in the leaves of plants. The most important of these is chlorophyll-a, chlorophyll-b also plays a role. The measured rate of photosynthesis as a function of absorbed wavelength correlates well with the absorption frequencies of chlorophyll a, but makes it evident that there are some other contributors to the absorption.

Chlorophyll - an overview | ScienceDirect Topics

Chl-a is the pigment that interacts directly in the light requiring reactions of photosynthesis. Chlorophyll b or Chl-b is different from Chl-a in only one of the functional groups bonded to the porphyrin. It is an accessory pigment and acts indirectly in photosynthesis by transferring light it absorbs to Chl-a. Alternating single and double bonds or conjugated bonds, like the porphyrin ring of chlorophylls, are common among pigments and are responsible for the absorption of visible light by these substances.

Concentration of photosynthetic pigments and …

Chlorophyll is essential for photosynthesis. It serves two primary functions in the photo systems. The major function of chlorophyll is to absorb light and transfer that light energy into chemical energy. There is more than one type of chlorophyll, each type plays a different role and has a unique chemical structure. Note that providing soluble silicon to plants results in increased concentration of chlorophyll in leaf tissues, resulting in enhanced metabolism resulting from increased use of available light energy.

there is widespread interest in chlorophylls ..

They serve as accessory light harvesting pigments,extending the range of wavelengths over which light can drivephotosynthesis, and they act to protect the chlorophyllous pigments fromthe harmful photodestructive reaction which occurs in the presence ofoxygen.
