Why is the grass green?

Chlorophyll is a green pigment and this gives the color to the grass and other plants.

The sky is blue due to the way that light is bent, it's called Rayleigh Scattering.  Sunlight is white and white light consists of all colors but when it hits our atmosphere the light is broken up into it's component colors by the particles in the atmosphere.  The shortest wavelengths don't make it through the particles but the blue light does - hence the sky appears blue when in fact it has no color ro it (it is after all, nothing but air and water).\n\nAs others have said - grass is green because of chlorophyll - the chemical in all plants and it just happens to be green.

Good question. \nGrass and most other plants are green because they contain a pigmentknown as chlorophyll. The chlorophyll is used in the process of photosynthesis where a plant produces sugar in the presence of sunlight. In fact the word 'photosynthesis' means literally to\nsynthesize or 'make' from light (photo).  \n\nI hope this helps :-D

Someone told me about this not so long ago...\n\nIts where the Sun reflects on the water or something for the sea\n\nand \n\nits green nearer the sand.. cus the sands yellow the seas blue so both colours mix together to make green\n\n(dont reli make sense)

Grass does NOT create energy - the previous answer is wrong.\n\nLike other plants, grass uses the energy of light to photosythesise carbon dioxide from the air with water from the soil to make sugars.\n\nThe sugars it makes can be converted into everything else it requires with the addition of various minerals (phosphates, nitrates, etc.) also from soil.\n\nThis is an autotrophic method of nutrition. Plants don't exactly feed.

I wonder why the grass is green \nAnd why the wind is never seen? \nWho taught the birds to built a nest \nAnd told the trees to take a rest? \nO, when the moon is not quite round \nWhere can the missing bit be found? \nWho lights the stars, when they blow out \nAnd makes the lighting flash about? \nWho paints the rainbow in the sky \nAnd hangs the fluffy clouds so high? \nWhy is it now, do you suppose \nThat dad won't tell me if he knows? \n\nPrashant Kushwaha, VII B \nRenukoot: Hindalco Vidya Niketan, UP

I have been told it is hail and the sunlight is refracted from  it and thats why it looks green.  The brighter the green the more hail is in the sky

The chloroplast cells absorb all other colors besides green. So green is reflected...

I believe they are green.  I know they are green, they look like leaves.

seaweed is green. seaweed is in the sea. It makes the sea look green.

There are a couple of theories of why the sky turns green during severe weather; however moreso with hail rather than tornadoes.  Some scientists believe that hail within a thunderstorm cloud bend the light at a degree to create a green tint to the clouds.  Others also believe that the mixture of the water vapor, rain, ice, and hail within the clouds give the cloud itself a bluish tint.  Therefore when you mix the tint with the yellowing and reddening sunset, you get a green tint to the cloud.

There are several vertebrates with blood that is green in color as a result of a buildup of the breakdown products of hemoglobin. This is a natural state for these species.

umm... giraffes are not green... maybe you were looking at some other animal..\n\n\njust so you will believe me... here's a picture of a giraffe!\n\n\nhttp://www.nilesafaris.com/images/giraffe1.jpg

Haven't heard the saying -- grass looks greener on the other side?

it has to do with the refraction of light. as ice is denser that water vapour that makes up regular clouds it refreacts at differing angles and densities hence that is why it is green.

I've heard that the sky turns a type of dirty greenish greyish colour before a severe hailstorm, or a tornado.  But I'd like to think that the sky would do that because of the types of clouds, and the absorption and reflection of light.  I've never seen it myself to say for sure. \n\nI've also been told that there are green flashes that apprear on the sea (but the sea level has to be right) around sunset.  I've never seen one of those either. Apparently, it's one of those must-see things.\n\nAnd then again, another place where greens exist is in the northern lights (Aurora Borealis)...  There are greens and they're gorgeous.  Now I've witnessed that, and it's simply GORGEOUS!!\n\nlike you said, there's always the good old rainbow!  I've seen that too :p\n\ncheers!!

It's the way the grass is cut to make it optically pleasing. It adds dimension for those in the stands.
