University Botany I : (Algae, Fungi, Bryophyta And Pteridophyta)
Prothallus grows by means of marginal meristem. c) Structure and types of
prothalli : Since the prothalli. are inconspicuous they are described as "green pin
heads". Dorsiventrally flattened gametophytes are prostrate on the substratum.

These prothalli are attached to the substratum by means of numerous rhizoids
and lead independent life (e.g., Pteris, Pteridium etc.) However, in some cases
the prothalli remain non-green and grow subterranean in the soil (e.g., Psilotum,
...

Botany For Degree Pteridophyta
Sometimes the lobes are arranged in a compact manner so that the spaces
between them are narrow and the prothalli appear to be solid. In other cases the
lobes are open and the prothalli appear to be spongy. This is the case when the ...

freer from contaminating blue-green algae that the cultures were correspondingly

Nevertheless, the ANOVA analysis of these data detected significant differences
depending on the origin; thus, the phytoecdysteroid productions of prothalli

from ...
