Ferns Q

[RDH]

In my notes I have that ferns differ from angiosperms and gemnosperms in:

1. no seeds vs seed

2. ferns have no cambium vs cambium in other two

I thought ferns have xylem and phloem and if so then cambium would be present could someone help clarify... thank you.

.Ferns contain large leaves which possess many vascular bundles. .Sperm must swim to the egg. Spores are enclosed in sporangia...
..
Hope this helps

Yah, that is what is confusing me I think my notes are from schuam, I know that ferns are vascular (Pterophyta) which would make them have a cambium which gives rise to xylem and phloem but I have two notes that contradict each other one states that,

The internal structure of ferns are similar to flowering plants consisting of conducting tubes of xylem and phloem.

and a second note that compares ferns to angio and gemno seperms stating

that ferns do not have cambium vs angio and gemno sperms having a cambium.

What I wrote is from Kaplan and Cliffs...I hate coming across contradictions.
