Which list represents a widely accepted proposed sequence in the evolution of land plants (from earliest to most recently derived groups)?
A
Bryophytes → seedless vascular plants → gymnosperms → angiosperms
B
Seedless vascular plants → bryophytes → gymnosperms → angiosperms
C
Gymnosperms → bryophytes → angiosperms → seedless vascular plants
D
Angiosperms → gymnosperms → seedless vascular plants → bryophytes
Verified step by step guidance1
Step 1: Understand the evolutionary timeline of land plants by recognizing the major groups and their order of appearance in the fossil record and evolutionary history.
Step 2: Identify bryophytes as the earliest group of land plants, which are non-vascular and include mosses, liverworts, and hornworts.
Step 3: Recognize seedless vascular plants, such as ferns and their relatives, as the next group to evolve, characterized by having vascular tissue but reproducing via spores rather than seeds.
Step 4: Note that gymnosperms, which are seed-producing plants without flowers (like conifers), evolved after seedless vascular plants.
Step 5: Finally, understand that angiosperms, or flowering plants, are the most recently derived group, characterized by flowers and enclosed seeds, completing the widely accepted sequence: Bryophytes → seedless vascular plants → gymnosperms → angiosperms.
