The difference between jelly and jam

Ok Chris, just for you, from The Straight Dope.

"Jelly is made from fruit juice and so has no fruit bits. Jam is made by boiling fruit and does have fruit bits. Preserves are basically the same as jam unless you buy them from Smucker's, in which case if it's got seeds in it it's preserves and if it doesn't it's jam. Marmalade typically is a citrus-based preserve, sometimes containing the rind, but other fruits can be used. Apple and peanut butter are called that because they bear a resemblance to dairy butter. But if you want to call it apple jam (as opposed to apple jelly, which is made from juice), fine by me."

And I was going to upload a picture of a strawberry, but ripway still is being stupid. So I didn't. But I will eventually, maybe.
