• I still don't understand Mendel's first law and second law! T_T One of them is about Independent Assortment and the other Random Segragation but I don't know what they mean exactly!

And!

• What does a transverse section of xylem look like?

Any help would be much appreciated! :uhhuh:

What you are talking about is Mendel's second law. I.A. and R.S. are the same thing!

First law states that factors go in pairs and in F1, factor exhibited is dominant, the other is recessive.

Well, to be simple, the transverse section of xylem looks like a WBC with no nuclease but a thickened membrane. Just draw a closed whatever then 'thicken' its outer membrane.
