A few incorrect statements

Originally it included all the colonial forms here grouped as the Volvocales, but since has been restricted to the spherical colonies, which form as a flat plate of cells and undergo a process of gastrulation before being released. These organisms have been studied by geneticists who hope that they may shed light on gastrulation in the development of other organisms, including humans.

1) Not all (do any?) form a flat plate before inversion, e.g. volvox forms a sphere, then inverts via a slit.

2) Gastrulation does not occur, as these are not even multicellular, let alone form an embryo. -203.171.67.232 04:45, 31 March 2007 (UTC)[reply]

I just expanded the article and it now states that simple Volvocaceans form flat plates and that more complex ones are truly multicellular and produce zygotes. However, I'm the first to admit my knowledge is very limited and my contribution to the article probably needs some help from an expert. --Fama Clamosa (talk) 11:25, 6 January 2010 (UTC)[reply]

Volvocineae?

[edit]

I've been reading "Elements of Stuctural and Systematic Botany" by Douglas Houghton Campbell (A Project Gutenberg EBook), published 1890. I know this is all very outdated material, but I'm trying to find out if what he describes as Volvocineae or "Green Monads" (characterized by being actively motile unicellular "plants" containing the group Euglena), is actually these Volvocaceae. The name seems similar enough, but I don't want to just guess. DancingHorses (talk) 10:09, 27 January 2011 (UTC)[reply]

I did a quick search. Palaeos.org Volvocales gives us some information; and according to Volvox: molecular-genetic origins of multicellularity and cellular, p. 14, What "A. Weismann called "natural order Volvocineae" is "Now (in 1998) more commonly called the family Volvovaceae, within the order Volvocales...". --Fama Clamosa (talk) 11:09, 27 January 2011 (UTC)[reply]
