why pterydphyta still classified into low degree plant eventhough it has leaves, root etc that is like the high degree plat have?

They’re ferns i.e. no flowers.

There are a few reasons why pteridofytas are classified as inferior to gimnospermes. Here is 2 that come to my mind now
– They do not have seeds, so it is less probable for the embryo to survive
– Unlike gimnosperes and angiospermes the plant does not consist entirely of the spropyte… We can still speak of an alternance in generations

terrible sorry everybody
June 11, 2005 at 5:05 am #24306
it’s alright, that’s why we have moderators :D.
For future reference though, I’d look into the text of the search results…not just the google summary.
P.S it’s pterophyta

As mush as I remember from lab notes, it is PTERIDOPHYTA.
It is mainly divided into these divisios:
The differences btw Pteridophyta and Spermatophyta: (from lab notes.)
1-There must be water for fertilization.
2-Gametophytes live independent from the beginning of its life or from some stage of its life.
3-Sporophytes grow from zygote to mature without inturruption.
4-There are no seeds.

I think it’s just a variant spelling. Both queries were redirected to the fern page in wikipedia.
June 12, 2005 at 11:31 am #24400
My bontany book also says pteridophyta. But many things are spelled differently in different countries. Despite this, I would expect something like this to be spelled the same everywhere because it is latin, no?
June 12, 2005 at 6:23 pm #24437
Pterophyta is a divisio of Pteridophyta. It writes like that in my notes.
June 13, 2005 at 6:21 pm #24519
What is a divisio? Do you mean division? As in part?

It seems strange. I never heard of such a thing… I wounder what is? A familiy, a class, an order?

I think it’s a translation thing 😉
Just remember. Poison thinks about the question in Turkish, then translates her reply into English. Then you read the English reply, then translate it into Romanian (I think that’s what you speak?). The language barrier is easily overcome, but minor translation problems still arise.
June 13, 2005 at 7:33 pm #24556
Yeah but that is latin. Don’t we all speak the same latin?

Language evolves, even if it is dead. In England, it is haemoglobin. In America, it is hemoglobin. No one’s going to translate and spell exactly as you do.

That’s also why sometimes questions are misunderstood when they are posted. It seems there are a lot of individuals from the Netherlands on here, doesn’t it?

Usually if a European posts a question, anyone from Europe can understand it perfectly. If an American posts, other Americans are able to understand better. There’s nothing wrong with it, and we should all try and post. But that’s just the way it is.

Yeah, nothing wrong with it at all. LET THE POSTING BEGIN!!! 😮

Hehe. It was just a friendly reminder to not poke at the way people post here. As long as the point gets across, no worries!
June 13, 2005 at 8:48 pm #24634
I wasn’t poking fun, I just was trying to put out a reminder that everyone isn’t from the USA as well. No problem 😉
June 13, 2005 at 8:49 pm #24635quote b_d_41501:
I know you’re not 😉
But we have had members in the past that would say things like, “It’s not hemoglobin, it’s haemoglobine!”

Divisio is a neutral taxonomic category especially used is plant systematics. I mean it doesn’t have an actual place. It can be everywhere. Some kind of grouping. It is not used so often.
I think ‘divisio’ IS in latin, at least that’s what our proffessors said. 🙂
June 14, 2005 at 7:17 pm #24751
I made a search in the web. I found results in my language. Maybe the old name of it is DIVISIO. It may be called DIVISION now.
I’ve seen that term here too:
http://www.dutchflowerlink.nl/engels/fl … lature.htm
It seems that both DIVISIO and DIVISION is correct. Have a look at that:

The Pteridophyta Divsion contains ferns. Ferns are plants with leaves, roots, and stems; but they do not have flowers like most plants. Ferns have special stems, called rhizomes, which grow sideways at the surface or underground. Many leaves grow from rhizomes and make fern colonies. Fern leaves are called fronds. Fronds have a petiole (leaf stalk) and blade (main part of leaf). Each leaf has smaller leaflets called pinnae. Instead of flowers, ferns have sori, which grow directly on leaves. Sori make spores, which travel by wind, water, or animal to new locations where new fern colonies can begin. Since they spread by spores, ferns do not have flowers, pollen, fruits, or seeds.
