Why is the Grass Is Green?
Close Look at Photosynthesis
Lets have a look through our Microscope at a typical leaf. To our human eye a leaf seems to be all green, but is that true, or is it an illusion. Looking through a microscope the individual plant cells that can be seen are not that green after all. Instead of being what we thought they are mostly transparent, but each cell contains around 50 to 100 tiny green dots. The correct name for these green dots is chloroplast's, this is where the light sensitive chlorophyll is found and where the process of photosynthesis happens.
So what is happening inside the chloroplast's?
The chloroplast is likened to a tiny bay with even smaller bags inside called thylakoids . And this is where the green colour comes from. The green chlorophyll molecules are embedded in the surface of the thylakoids, these molecules are not embedded at random but are carefully arranged, this is called photosystems.
Two Types of Photosystems
Most green plants contain two types of photosytems, these are known as PS1 and PS2. Each as specific jobs to take care of, in the steps of photosynthesis.
Absorbing The Sunlight
When the sunlight hits the surface of the thylakoid, PS2 chlorophyll molecules are ready to catch it. PS2 molecules are especially interested in catching the red light of a specific wavelength. Again in the thylakoid the PS1 arrays are catching the light from a different longer wavelength. At the same time chlorophyll and other molecules for example carotenoids are absorbing violet and blue light.
So now the big question, why is the grass green?
From all the wavelengths that fall on plants only one light is useless to them, and this colour is simply reflected away, like a mirror.
You guessed it, the colour of light that is useless to the plants in the green light.

Grass and other green plants have a chemical called chlorophyll, and its special structure allows it to specifically catch blue and red light. All light has energy, and chlorophyll absorbs the colors that have the correct energy to help power the plant’s machinery. The plant can then turn carbon dioxide and water into glucose, a sugar. The leftover light, mostly green, bounces off and reaches our eyes; since there’s a lot of chlorophyll in plants, we see them as being green.

Grass and most other plants are green because they contain a pigment
known as chlorophyll. The chlorophyll is used in the process of
photosynthesis where a plant produces sugar in the presence of
sunlight. 'photosynthesis' means literally to
synthesize or 'make' from light (photo).

Why Is Grass Green
Grass is green because it is envious of trees which are much taller and don't get stepped on like grass does. Trees don't get mowed every week in the summertime and sprayed with Weed-be-gone.
Also, grass is green because it is filled with chlorophyll not chloroform that is a green pigment that reflects green light from the sun and absorbs the other colors. Yeah, right, if you believe that one, you're pretty green yourself.
Green grass actually comes from elves, who are themselves green. They sprinkle faerie dust over the earth at night and some lands on plants and turns them green. In the Winter, the elves hybernate so grass is usually brown during this time. But, in Spring time, the elves come back out and start sprinkling again and tinkling all over the grass, which is great fertilizer.

The chlorophil in the grass that absorbs sunlight is green, making the grass green. This is why the leaves on many trees are green, because they absorb sunlight, not the tree itself, otherwise the wood would be green.

Grass, as well as a lot of other plants, are green because they contain a pigment known as chlorophyll. Chlorophyll is used in the process of photosynthesis, where a plant produces sugar in the presence of sunlight (makes its own food, and food for others).

because of the suns pigment
all of the suns rays (since it's white, it has all the colors) go through the grass and into the soil.
one of the color that doesn't go through it green
thus, grass is green

"Photosynthesis"
Plants don't have mouths and chew foods like we humans do in order to process and utilize energy. Instead, plants use the sunlight to process their nutrients and absorb carbon while releasing oxygen. Plants also contain cholorplasts which houses the chlorophyll which in turn gives the plants its green color when when it absorbs the sunlight or when the sunlight reflects on its plant surface. Hope this info helps some. My Bio lessons are somewhat crappy.
