Functions of plant parts?

Funny,but I have the New Western Plant Encyclopedia sitting right in front of me. I really,really would love to give you all the information it gives in the book, but how are you going to learn about them for yourself if you have someone else tell you instead of studying it? I think you would get allot more out of the lesson if you went to the Library and did some research. It probably will come in handy later on it life. Believe me, I would help you out but I keep seeing my Dad standing behind me looking over my shoulder,and Dad says no,let them learn it on their own.( Dad is a Ghost now)
