Grass and most of the 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. In fact the word 'photosynthesis' means literally to synthesize or 'make' from light (photo).

There are, of course some plants which do not contain chlorophyll, and these generally get their nutrition (food) by other means. Some examples are the fungi which decompose dead, and sometimes living, tissue, for their food. You will find that a green plant needs light to make food. If the source of light is cut off, the plant dies.

Mushrooms, which are fungi, do not require light to make food (they decompose matter, as mentioned above) and you can find mushrooms growing in almost complete darkness. Hope this helps...
