Question

You are hiking in a forest and come upon a mysterious plant, which you determine is either a lycophyte sporophyte or a pterophyte sporophyte. Which of the following would be most helpful in determining the correct classification of the plant?

A) whether or not it has true leaves
B) whether it has microphylls or megaphylls
C) whether or not it has seeds

Answer 1

Answer: choice A

Step-by-step explanation:

The main difference between pterophytes and lycophytes is the presence of true leaves(pteropytes) and lychophylls(lychophytes). Having lycophylls is a synapomorphy for the lychophytes.

Neither of these clades have seeds.
