why the color of leaf is green?no

Chlorophyll is a pigment found in the leaves of most
plants, specifically in the chloroplast, a specialized part of a leaf cell. When a leaf
is exposed to sunlight, the chlorophyll absorbs red and blue wavelengths of energy and
reflects the green wavelengths. This is the actual reason for the leaves appearing to
have a green color. In the autumn, as the chlorophyll ceases to reflect the green, the
leaves then stop having a green color. Other pigments found in leaves are then able to
reflect other colors, such as the oranges, reds, and browns observed in fall
leaves.

As the chlorophyll absorbs the energy from the red
and blue wavelengths, that energy begins the process of photosynthesis within the
cells.
