Land Plant Origin Among the Charophyte Green Algae

This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.

State

Land plants descended from a freshwater charophyte green alga, a lineage grouped with land plants in Archaeplastida by shared chloroplast ancestry.

Show

Traits linking charophytes to land plants include phragmoplast-guided cell division, plasmodesmata, and sporopollenin, corroborated by DNA sequence comparison.

Watch for

A living charophyte is not land plants' ancestor, only a relative of the lineage that gave rise to them.
