Answer:
The longer answer lies in the details of photosynthesis, the electromagnetic spectrum, energy and “special pairs” of chlorophyll molecules in each plant cell. ... As such, plants look green because they absorb red light most efficiently and the green light is reflected.
Explanation:
Green plants are green because they contain a pigment called chlorophyll. Chlorophyll absorbs certain wavelengths of light within the visible light spectrum. ... Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants

Explanation:
Vegetation on soil protects the soil from erosion because its roots and root hairs help bind the soil particles together. This occurs mechanically by binding soil into crumbs and also chemically by providing organic matter that binds the soil particle into humus that holds moisture. The soil becomes heavy to be carried off by wind erosion. Trees also break the down flow of water hence reducing the capacity of runoff to carry soil sediments.
