A student asked me today what fern is and I had no idea how to describe it. What's fern? A fractal-like flower??? So I tried searching 'fern' on pidic.com (it's a picture dictionary) and luckily there was a picture of fern. As soon as I showed the picture to him, he got it. Now I wonder, when is it actually better to have word definitions over "picture definitions?"
What is fern???
here is a link : you can read whole that info which is written there: http://en.wikipedia.org/wiki/Fern
When was Wikipedia created? In my opinion, it's far the best place to look for info.
wikipedia is super for information the link is www.wikipedia.com. You can find whotever you want and if you are not satisfacted with information which is included you can correct it or to write much more for what you know.
