Do Charophytes Have Motile Sperm?

The limited capacity of charophyte algae for dispersal via motile sperm, therefore gave way to terrestrial colonization via dissemination of durable spores shed by increasingly complex and dominant sporophytes (reviewed in Niklas & Kutschera, 2009).

Do charophytes have flagellated sperm?

Charophytes form sporopollenin and precursors of lignin, phragmoplasts, and have flagellated sperm. They do not exhibit alternation of generations.

Are charophytes motile?

Aside from being motile unicells, they have a "wall" made of overlapping diamond-shaped scales. Furthermore, they have laterally-inserted flagella that emerge from a crypt.
