Second bite

From: SNALICE at aol.com on 1997.04.30 at 19:42:44(690) And the meaning of heterotroph? I found that "heter" means "different", "not alike", and "trop" means "turning towards" as to the sun (I couldn't find "troph"). How does this translate? If I had to guess: Such an inflorescence would be unlike others since it would not follow the sun's course? Sue Zunino

From: "Richard Mansell (BIO)" <mansell at chuma.cas.usf.edu> on 1997.04.30 at 21:15:00(691) Heterotroph refers to those organisms that cannot produce their own food source, (glucose). Thus fungi, animals etc are considered heterotrophs. Many bacteria are heterotrophs but some are also photoautotrophs (use light to produce sugar), or chemoautotrophs (use chemical compounds which they oxidize to release energy which in turn they use to make sugar). Sounds like fun stuff, huh! Hope this helps.

From: eduardo gomes goncalves <eggon at guarany.cpd.unb.br> on 1997.05.01 at 01:57:39(693) Dear Sue, In botany, heterotroph simply means: Those organisms (or organs) that aren't able to produce their own food by means of photosyntetic activity. The word "troph" concerns the form of nutrition. Since the inflorescences are mostly aclorophyllous (now that all aroidelers know what it means), they are essencially heterotroph and drain lots of energy from the mother plant, delaying the production of new leaves. This situation seems to get worse in strongly thermogenic inflorescences, like those of Alocasia, Philodendron, etc. Hope the above helps, Eduardo. +More P.S. Before any of you try a third bite, Thermogenic means: Something able to produce heat!!!

From: "Richard Mansell (BIO)" <mansell at chuma.cas.usf.edu> on 1997.05.01 at 02:50:58(696) A second effort. Heterotroph (biol) capable of utilizing only organic materials as a source of food, as most animals and some plants. (opposed to autotrophic). Hetero - from others, not from self. Trophic: of or pertaining to nutrition; concerned in the nutritive processes. Please do not stop asking questions; we shall keep trying to clarify and should continue to do so. Thay way, everyone learns. Dick +More -- Richard L.

From: "Jane M. Whitehill" <whitehil at mobot.org> on 1997.05.01 at 18:10:55(699) heterotrophs are like us - organisms that eat other organisms to stay alive. Plants that make sugars themselves , that is, green plants in general, are autotrophs. +More On Wed, 30 Apr 1997 SNALICE@aol.com wrote: > And the meaning of heterotroph? > I found that "heter" means "different", "not alike", and "trop" means > "turning towards" as to the sun (I couldn't find "troph").

From: SNALICE at aol.com on 1997.05.01 at 18:15:38(700) Edwardo, Well I wasn't going to take a third bite, because I recall a conversation going on about Philo. inflorescense emiting heat at such an elevated degree, so as to be able to feel it when passing by, but now I think I understand why everyone contemplates chopping off the inflorescence, so the leaf will be better able to produce the energy ( which it previously made (being autotrophic), and stored in the corm and the inflorescence does not make (being heterotrophic), but uses) needed to feed back into the corm. Is this correct? I hope you all understand this sentence, because I'm not sure I do. Thanks to all, Sue
