Chapter 29, Problem 1COQ
Summary Introduction
To determine: The difference in the environmental conditions experienced by early land plants and ancestral streptophyte algae.
Introduction: Modern plants and the green algae, which are most closely related to them, are together called streptophytes. Molecular and evolutionary studies have shown that modern plants have originated from their algal ancestors (green algae).
