Question

why the leaves of the Plants are green​

Answer 1

So, plants and their leaves look green because the “special pair” of chlorophyll molecules uses the red end of the visible light spectrum to power reactions inside each cell. The unused green light is reflected from the leaf and we see that light

Answer 2

heya, buddy !!

➦In the blue part of the electromagnetic spectrum and the red portion, chlorophylls absorb light most strongly. In comparison, it is a weak absorber of the green and near-green parts of the spectrum that it represents, creating the green colour of tissues containing chlorophyll. In the photosystems of green plants, two forms of chlorophyll exist chlorophyll a and b.

For photosynthesis, chlorophyll is important, which helps plants to absorb light energy.

➦The Chlorophyll molecules are organised in and around photosystems that are embedded in chloroplasts' thylakoid membranes. Chlorophyll performs three roles in these complexes. Light absorption is the feature of the vast majority of chlorophyll (up to several hundred molecules per photosystem). Having done so, these same centres perform their second function: the transfer of the light energy to a particular chlorophyll pair in the photosystems' reaction centre by resonance energy transfer. This pair affects chlorophylls' final feature, separation of charge, leading to biosynthesis.

➦The Photosystem II and photosystem I, which have their own different reaction centres, named P680 and P700 respectively, are the two currently approved photosystem modules. These centres are named after the limit of their red-peak absorption wavelength (in nanometers). In each photosystem, the identity, function and spectral properties of the chlorophyll forms are distinct and determined by each other and the protein structure that surrounds them. These chlorophyll pigments can be divided into chlorophyll a and chlorophyll b after they have been removed from the protein in a solvent (such as acetone or methanol).

We know that, The electron flow provided by the chlorophyll pigments of the reaction centre is used to pump H+ ions through the thylakoid membrane, creating the chemiosmotic potential used primarily to produce ATP (stored chemical energy) or to reduce NADP+ to NADPH. NADPH is a universal agent used both in sugars and in other biosynthetic reactions to reduce Carbon dioxide.
