photosynthetic pigments

Photosynthetic Pigments - Molecules of chlorophyll-a, chlorophyll-b, carotene and xanthopyhll are situated in the thylakoid membranes. For light energy to be used by living systems, it must first be absorbed. A pigment is any substance that absorbs light. Chlorophyll, ..

The photosynthetic pigments chlorophylls are present in the leaves because of which the leaves are green in colour and are called the photosynthetic organs. The leaves have the following structure: As shown in the diagram, the mesophyll region of the leaves has cell..

Blue green algae contain in addition to chlorophyll, other photosynthetic pigments, such as Phycobillins. Phycobillins are of three types phycocyanin (blue), allophycocyanin (blue) and phycoerythrin (re..

They are pigments capable of absorbing radiant energy of the sun. Pigments are chemically porphyrin molecules which have a metal ion at the centre. The metal ion in haemoglobin is iron and in chlorophyll, it is magnesium. There are two types of photosynthetic pig..

The photoautotrophic bacteria possess photosynthetic pigments in membrane bound lamellae (or thylakoids) and utilise solar energy. The bacterial photosynthesis is different from that of green plants since here water is not used as a hydrogen donor. Hence oxygen is not release..

It is so called as it takes place only in the presence of sunlight and hence is a light-dependent reaction. Robin Hill, an English biochemist conducted studies on isolated chloroplasts to understand the mechanism of light reactions. Hence, it is also called Hill's reaction. During this stage, the ..

These are a group of peculiar organisms which share characteristics of fungi and animals. Hence, they are also called as Mycetozoa . In the modern classification they are described as protistan fungi . Most examples of slime moulds are terrestrial and occur in cool, moist and shady places in decayi..
