The text here was deliberately indecisive about whether the green algae should be placed among the Protista or the Plantae, since it is done both ways. The algae are of definite affinity to the higher plants, sharing common pigmentation and ultrastructure, but have a typically protozoan organization. Should the table (as per ciliate, dandelion) list one kingdom, the other, or both as parents? The same question applies as to whether the chytrids should count as fungi.

[edit] Tax box

See my sandbox for a suggested update to the taxbox. I am happy to keep the Plantae Kingdom though. Onco p53 23:45, 24 Jan 2005 (UTC)

I am going to do it then. Chlorophyceae
Pedinophyceae
Picocystophyceae
Prasinophyceae
Trebouxiophyceae
Ulvophyceae
I'll keep these here temporarily since this is going to be moved off the main page Onco p53 03:48, 26 Jan 2005 (UTC)

[edit] Kingdom Viridiplantae

How about placing green algae in the Kingdom Viridiplantae? That would account for both the Kingdom Protista and Plantae characters of it.

Hi, we have kind of been over this discussion here please add more comments if you wish. Onco p53 06:24, 16 Feb 2005 (UTC)
Even if they are not in Viridiplantae they are still in Plantae though. Right? There divisions are.--Kupirijo 12:42, 19 October 2006 (UTC)

[edit] Classification

OK perhaps I'm too old. But just keep them as Chlorophyta! See: Hrady, F.G. and Guiry, M.D. A Check-list and Atlas of the Seaweeds of Britain and Ireland. 2006. British Phycological Society, London ISBN 3 906166 35 X Osborne 14:48, 13 February 2007 (UTC)

[edit] Conjugation and subheadings

I added an image of conjugating green algae and I put subheadings in. This required me to move text around to improve readability. Sorry if it ruffled anyone's feathers. Rozzychan 14:09, 17 February 2007 (UTC)

[edit] Is green algae harmful

Is green algae the stuff that grows in water filters? If so, is it harmful and is there a way to prevent the growth? CharmeC 00:11, 19 February 2007 (UTC)

Green algae are a large group of algae - both marine and freshwater, many are microscopic others are up to 1m. long. There are "about 1000 - 2000 species of green seaweed." ref: Thomas, D.N.2002. "Seaweeds." p.11. ISBN 0 565 09175 1 . The "stuff that grows in water filters " will include green algae probably, possibly more than one species. It initself is not harmful, however I suppose it may trap other growths and particles which may be harmful. I trust you will not wish to kill all green algae in the world!

[edit] Tummies

Question regarding the first line of this article, "Green algae are microscopic protists; found in all aquatic environments, including marine, freshwater and brackish water and tummies". Tummies? Possible vandalism? SabreWolfy 02:03, 4 March 2007 (UTC)

Plain stupid or immature. Anyway they will not grow in "tummies" without light and floating in acid! Osborne 13:59, 12 March 2007 (UTC)

[edit] Green Algae OR Chlorophyta

There are articles on Brown algae (Phaeophyta or Heterokontophyta?); Red Algae (Rhodophyta) so I suppose this should be "Green algae" (Chlorophyta)q.v. Osborne 13:01, 10 May 2007 (UTC)

[edit] Classification

This is a bit confusing! In the "Green algae" should I leave the classification and copy in the classification from the Chlorophyta? Perhaps I should. So there! Osborne 13:05, 10 May 2007 (UTC)

[edit] Origins

The section on origins is confusing and the flow is not intuitive. The bit about double membranes should presumably lead to a statement about endosymbiosis. Can somebody who understands this better than I rewrite this section? Presumably what needs is meant is that green algae share descent with reds and glaucophytes, and that the pigments of greens are not necessarily indicative of which specific cyanobacteria was the endosymbiont, but rather a case of convergence?Spamburgler (talk) 02:55, 23 January 2008 (UTC)
