chemoheterotrophic plants

Postby Jules19 » Mon Jan 18, 2010 1:53 am

The glossary in my text book says the kingdom Plantae is "a multicellular, photosynthetic eukaryote, etc....."
but I heard about parasitic "plants" that are chemoheterotrophs. So why are these classified as plants if they aren't photosynthetic?

because that is acquired, but originally they were photosynthetis. That's like if you asked, why to say, that dolphins are mammals, when they live in water? Why not say, they are fishes?

Cis or trans? That's what matters.

As far as I know, photosynthesis is not the main criteria for an organism to be classified a plant despite it being perhaps the most prominent feature of plants. Plants are classified by a combination of several biochemical features, such as typical metabolic pathways, genes for clorophyl(?) and the composition of the cell wall etc. Also, I think even such parasitic plants that have no visible clorophyl still have the genes needed for its production (and most can under some conditions produce little of it).

I'm not 100% certain of this, though. Let's see if someone else knows more.
