Question

Plants and green algae have monophyletic lineage. Justify this statement.

I'm waiting for your answer!!

Answer 1

The green algae and land plants form a monophyletic lineage (the chlorophytes) that contains both protistan and higher taxa (Graham, 1996). An important issue regarding the evolution of this green lineage that still remains in question is the identity of the green algal (i.e. flagellate) ancestor of land plants.
