Biology as level labelling

Can someone tell me where the vascular bundle is and wether this drawling is right ? It’s not a nice drawing but it’s just a question I want to ask
The images are attached below

This shows one bundle - I would say this is a cross-section of a stem (in which the bundles are arranged in a rough circular shape producing in 3-D a (incomplete) cylinder, which is the best way to resist horizontal forces = wind. In the root the bundles form a central rod which can easily push downwards through the soil (vertical force).

So is my picture correct for one vascular bundle and is the one u circled the vascular bundle
The one I have circled, YES.

Your drawing looks v different from the micrograph in overall shape PLUS you have drawn a number of blobs with no labelling, so impossible to tell!

Are the three small circles I drew representative of vascular bundles , I know it’s not my real picture , just a sample
Plus can you circle the vascular bundle here too please

I can show you with my own pics and hand-drawn diagrams - easier if you confirm that the section given in the micrograph is part of a stem (or otherwise)

No I just want to know if I write vascular bundle for those three circles , if it’s correct ? Ps that’s a leaf I guess

Sorry to be blunt but the diagram you have drawn HAS NO CORRELATION WHATSOEVER to the cross-section microscope view given.

So there is no way of knowing what you are trying to show by "the 3 small circles".

SO the answer is INCORRECT.

I am happy to explain how the whole thing works if you would like to learn.

Ok wait let me tell you how I drew the diagram
No probs!

Look I’m just trying to draw a plan diagram , I don’t really need any details , and that’s the drawing

No this is incorrect - the single larger blob [to the left of the 3 small ones] is the vascular bundle! The "lump" where all those four shapes are located is the vein you see running along the middle of a leaf, and each vein or branch of it HAS ONLY ONE VASCULAR BUNDLE.

Ok can you please tell if without the labelling , the drawing is correct ? And if you were to draw it , how would you do it

Thanks for the rep!

Drawing leaf x-section B.jpg

This is how I would draw it - if you have limited time, miss out the xylem and phloem individual tubes and other labels.

Is my structure correct if looking at it without labels ?
And thanks for the picture , but yours is not a plan diagram I guess and why is there only one vascular bundle

Ok - just saw your latest post - I am not a botanist and you are not an artist :colondollar: - I have not come across vascular bundles being split into parts as in your latest upload - in this case I would label all four of your "circles" (1 large and 3 small) as vascular bundles - you can tell this is the case in the micrograph (latest one) cos u can see the xylem tubes [with thick dark borders] in all of them - having said that, I would draw your diagram with the shapes and location of the bundles a bit more similar to those in the micrograph.

In summary, I need to do an MSc in Pharmacognosy [in which you learn about the micro-anatomy of various plants], and you need to do a BA in fine art!!!:wink:

BTW, well done! - you have taught me something!

Not a fan of art honestly , but hahaha I will take the advice , btw what have I taught u ? I’m curious
And so is my picture right overall ? If not labeled the way I did

Hi again, I had only looked at a handful of pics of leaf cross-section, and had ALWAYS seen only one vascular bundle per vein/venule - you have taught me that some species of plants have more than one bundle per vein - I suppose 4.8 degrees is not enough, especially as one of my nicknames is Sheldon!!
