Leaves of most plants appear green because the chlorophyll present in it:

Step-by-step solution

Chlorophyll, the pigment responsible for the green color of leaves, primarily absorbs blue and red light wavelengths from the visible spectrum. It absorbs these wavelengths to facilitate photosynthesis, which is the process of converting light energy into chemical energy. The green light, which is not absorbed effectively by chlorophyll, is reflected and gives leaves their characteristic green colour.
