3. The evolutionary transition of plants from an aquatic green algal ancestor (Charophytes) to terrestrial environments required massive structural and reproductive innovations to survive desiccation and gravity.

f) Analyze how the dominant life phase shifts as you move from non-vascular plants (Bryophytes) to seedless vascular plants (Monilophytes/Ferns) and finally to seed plants (Gymnosperms/Angiosperms). Explain the evolutionary advantage of maintaining a reduced, protected gametophyte within a dominant sporophyte body in a terrestrial habitat. (5 points)
