Measurements of metabolic activity and water-use-efficiency during dehydration and rehydration of 45 cheilanthoid samples showed that different species had different levels of D-T. Results suggest that D-T is ancestral in cheilanthoid ferns ...

Isozymes in Plant Biology
Most pteridophytes are homosporous, producing one type of spore that
germinates to produce a potentially bisexual gametophyte. The homosporous
pteridophytes are the whisk ferns, Psilotum and Tmesipteris (Psilotophyta); the
lycopods, ...

The plants may be homosporous i.e., produce only one type of spores (e.g.,
Psilotum, Lycopodium, Equisetum, Pteridium, Pteris, etc.) or heterosporous i.e.,
produce two different types of spores smaller microspores and larger
megaspores (e.g. ...

By the end of the isozyme era, it was clear that the previous explanation for high

neopolyploidy—was no longer supported. Alternative explanations that do not

Handbook of Plant Science
Oogamous reproduction may be heterosporous or homosporous. Heterospory,
found in all seed plants, features a female gamete, the egg, that is large and non-
motile (the megaspore), while the male sperm (microspore) is often much smaller
