Tracing One Lineage from Charophyte Ancestor to Angiosperm Flower
Captions available
The idea
This capstone traces the plant lineage from a shared charophyte green algal ancestor through the four land adaptations, vascular tissue, and the seed habit to a modern angiosperm's double fertilization.
Where people slip
Each stage in this trace built on the one before it without discarding it — a modern flowering plant still alternates generations, still guards against desiccation with a cuticle, and still traces its chloroplast to the same primary endosymbiotic event as its algal ancestor.
