“Ceratopteris spores, like fucoid zygotes, divide unequally to produce a small rhizoid cell and a larger cell that develops into the thallus.”

“The thallus and rhizoid can be distinguished by their different patterns of cell division.”

“The genera are characterized by the sporangiophore and sporangial features and their relationship to and appearance of the rhizoid structures.”

“It is likely that the rhizoids absorb water, but only because almost everything in a moss absorbs water.”

“The other end manifests an array of long, filamentous rhizoids that have the appearance, and apparently serve the same function, as root hairs.”

“The zoospore encysted and within 24 hrs branched rhizoids formed and the cyst began to enlarge to form a zoosporangium.”
