Question

    • Photosynthetic organisms introduce chemical energy and fixed carbon into the ecosystem by using light to synthesize sugar
    • The lamina is used for absorption of sunlight and carbondioxide during Photosynthesis.
    • Pigments are the most that imparts colour and absorb light at some specific wavelength and reflect back the unabsorbed light.
    • Photisystems have large complex of pigment and protein molecules present within the plant cells , which play primary role during the light reactions of photosynthesis
