The adhesive attaches the color to the fabric. Biological classification of plants and animals was first proposed by Aristotle on the basis of simple morphological characters. Many of these compounds are coloured due to the absorption of light energy by electrons in d orbital subshells, meaning we see colours depending on which wavelengths of light are not absorbed by the compound.  Enhancing naturally occurring colors. N. 1 Structure of some carotenoids. Dyes 5. However, the most useful classification is by color (white, transparent, or colored) and by function. In Chlorophyceae there are 2-6 thylakoids per granum and the pyrenoids are covered with starch plates. 1, NIC-1998 was updated keeping consistent with ISIC Rev 3. The pigments are non-toxic and resistant to solvents, chemicals and elevated temperatures. The photosynthesis process makes use of the green pigment called chlorophyll along with some other form of yellow and red pigments.
