Question

Why the Grass is Green ?

Answer 1

Why the Grass is Green
It is necessary to understand how light works before we understand what makes the grass and other plants green. Light is made up of a spectrum of colors. All things or objects are colored in a certain way. This happens when light is either absorbed; reflected or transmitted by that certain object.

An object is black when all colors of light are absorbed. An object has a certain color because that object absorbs the other colors of the rainbow. This reflects or emits the color we see.

The grass or other plants are green because it absorbs all the colors of the light. The only exemption is the color green. This is exempted because grass or most green plants contain Chlorophyll.

Chlorophyll is a green pigment. It is known to help most plants process their food. The process is called ‘photosynthesis’.

‘Photosynthesis’ enables plants to use energy from sunlight. It will aide in the production of glucose or sugar. This is the food for the plant.

Chlorophyll in plants absorbs mostly the blue and the red light. This contains the correct energy. It helps the plant produce its own food. It also aids in ‘photosynthesis’.

The left over energy from the sunlight is emitted out of the plant. This is energy called green light. Thus, the backfire of green light energy is what makes us see the grass and other plants green.
