Give 4 examples of plant characteristics in the early paleozoic.(lower)?

Question

Early Paleozoic period (lower)

Answer 1

Cooksonia, consisted of small naked, dichotomously bifurcting axes bearing terminal sporangia.

Baragwanathia is a much more robust plant consisting of up to 30 cm long axes with spirally arranged leaves and it has been described from the Upper Silurian of Australia.

The Rhyniophytes are a group of early land plants originally described from the Rhynie Chert. They have naked, dichotomously branching axes with terminally positioned sporangia.

The Zosterophyllophytes are a group of Early to Middle Devonian plants with mostly dicotomously branching axes and laterally inserted, usually more or less kidney-shaped sporangia.

Answer 2

I have given this question considerable thought. Considering we are dealing with the "pale"ozoic period and the plant characteristics thereby, I surmise the following: We have the pale green, pale brown, pale red and, of course the pale yellow.
The zoic period still remains a mystery, however the fact that it begins with a "z" allows us thinking kind to associate the zoic period with, whatever, the last letter of the alphabet.
