After reading this article you will learn about the chemical structure of chlorophyll. Also learn about the absorption spectra of chlorophyll, with the help of suitable diagrams. A green pigment within the chloroplast (Fig. 3.40). It absorbs light energy. Now, it is a question of interest, how these chlorophylls absorb light energy? Chlorophyll traps the light energy, hence called as [...]
In this article we will discuss about the tests for spectrophotometric determination of chlorophyll and carotenoids. Extraction of Chlorophyll and Carotenoids: Although chlorophyllous and carotenoid pigments may be extracted readily in organic solvents, for many algae, extraction is not complete unless the cells are ruptured. Therefore, filters should be placed with forceps into the base of a glass for drinking [...]
Useful notes on the morphological features of the chlorophylls! The cell wall: In Chlorophyceae, the cell wall usually consists of 2 or 3 layers. The innermost layer is of cellulose and encircles the protoplast. The second layer consists of pectic compounds of pectose sometimes associated with cellulose. In the case of Oedogonium and Cladophora, the outermost layer of the cell [...]
