The "cotyledons" are what's left of the seed after it splits open and the tap root grows downward. The seed, with it's split, open, shell (like a little "hat") gets pushed upwards, above ground. The shell falls off revealing the cotyledons or "seed leaves", they are like the two halves of a peanut or a dried bean. They contain all of the stored energy to get the plant going - shriveling up and falling off in the process. They are the first two, small, round, thick leaves. The plant continues to grow upward from these "seed leaves" untill you get the first set of, familiar, "true leaves" (narrow and pointy with serrated edges, usually with three "fingers").
So, here's to the Cotyledons!!! We hate to see them go - but hey, that's what they're here for!
