photosynthetic chlorophyll

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 pigments - ch..

The photosynthetic pigments chlorophylls are present in the leaves because of which the leaves are green in colour and are called the photosynthetic organ..

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. Chloroph..

Photosynthetic Apparatus - 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: Histological Details of a Leaf in ..

The variegated leaf contains chlorophyll only in patches and hence the photosynthetic activity is restricted to those patches. Thus, only those areas give blue-black colou..

Wavelength of light between 400 nm and 700 nm is most effective for photosynthesis. This light is called photosynthetically active radiation (PAR). Comparatively more photosynthesis occurs is red and blue regions though others have significant net photosynthesis. Light has maximum effici..

It is a diverse group of algae, most of which are fresh water forms. A few are marine forms. The plant body may be unicellular and motile (as in Chlamydomonas) or colonial and motile (as in volvox) or colonial and non motile (as in hydrodictyon) or filamentous (as in Oedogonium and Cladophora). Sha..

It comprises the living part of the environment, which includes the association of a number of interrelated populations belonging to different species in a common environment. The populations are that of animal community, plant community and microbial community. Biotic community is distinguished i..
