1) Plants look grown beacuse light coming from plant get refracted and hence, only green light reaches out eyes.
Chlorophyll is also responsible for giving green color to plant.
2) Respiratory system of earthworm is its skin because earth worm have to live in water as well as in moist are, so thier lungs function can't be possible.
