<~ö All about cacti ö~>

[mith]

Invitro means "in glass" or in test tubes.
Did you mention something about a cacti gun?

[Dr.Stein]

I DO know the meaning of in vitro. I just thought that the term is not properly used here... So, there will be cacti in vivo... oh ahahahhaa

Yes, cacti gun, why?

[mothorc]

There are two kind of "cacti" so you must distinguish: "true cacti" and "euphorbiaceae", they have the same shape. When grafting, you much graft the same family together.
I have some trouble with my photograph that cacti grow in small bottles (look lovely).

[Dr.Stein]

mothorc: Yes, not only mistake members of Euphorbiaceae for true cacti (Cactaceae), people also mistake some members of Crassulaceae or Apocynaceae for cacti.

Look at my cacti pictures above, can you distinguish which one is a cactus and which one is not a cactus? Awawawawawaaa... please forgive my 'teacher's instict', that I sound like giving you a homework

[Poison]

I love cacti too. I have some in my room.

[mothorc]

I known you re a teacher, I know.
Nobody can't distinguish any thing by looking your picture. But with real cacti, we can easily distinguish them by flower classification or latex.
I think you don't want to be told to distinguis invitro, invivo, exvitro and exvivo.
Please don't ask me as teacher 's way.(this forum is not for you and me)

can you distinguish which one is a cactus and which one is not a cactus?

If i'm not wrong then the first and the last two are not cacti

I am sorry but what happened to you? I just tried to make fun here with the quiz. That's because I found this topic is interesting. I myself cannot distinguish them quickly as a lucky guess. Here, we are having fun and learning in the same time. Wouldn't it be a nice thing? I do think so. We do not need to sit in the classroom, staring at the board. We can learn with laying on our bed, listening to music, eat and drinks maybe.

I am sorry if I offended you, I really did not mean that. I come here to learn together, out of my profession, if I know I will tell, if I do not know I will ask. I am not a living dictionary, I am just a human being with my limited capacity. It means that it is normal if I forget things and I do not know about this and that. That's why I asked.

And, I think we all know, during the study, there is right and wrong. If someone makes a mistake, by accident or because she/he does not know the correct one, and we know the right one, I am sure we will tell her/him the right one. All we need in studying is open-mind.

In this case, the term in vitro cacti is totally new for me. I am honest. That's why I asked about it. If then it is not a proper term, I still have no idea, let's search for the best term for it. That's what I expected. That's all.

Last but not least, I do apologize for all my mistakes. I really did not mean that. Thank you. Shake hands, please?

[mothorc]

Sorry, I think I had some trouble in my lab so I think you was joking, I mean we are friend.
now I m in class, I will edit about "invitro" later for you .

[Dr.Stein]

Sure, we are friends. Thank you and good luck for your study
