The bryophytes are of botanical interest because their ancestors apparently were among the first  land plants. The existing species today have some green algal features and some vascular plant  attributes making them intermediates—more complex than green algae, but not quite vascular  plants. Once thought to be monophyletic, the bryophytes are now recognized as having three  independent lineages.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
