I like to think of a plant’s roots as an analogy for the knowledge required to create something. As a weird example, a web app may be like the exposed plant above ground while the roots are that developer’s knowledge. The plant is what others see, but the roots are the intricate system that was required to create the plant.

That would probably produce a distorted image of the root system.

On the contrary - I think you'd get an accurate image of a very distorted root system!

Me fail English? That's unpossible! :)

But yeah, that's what I mean.

no wonder the damned things keep coming back!

How much of the root needs to still be in the ground for it to be able to grow back?

New rosettes arise from buds at the crown and upper taproot so anything deeper than about 10cm is very unlikely to come back.

That drawing is from a very rare specimens too. Most dandelions do not grow that deep.

Collection history page has a photo for part of the process https://images.wur.nl/digital/collection/coll13

The image says it took 6 persons 5 days to expose the roots of "Pinus cembra".

They usually are. It’s a process akin to archaeology where they have to carefully wash away the dirt from the root system, measuring as they go. The problem with this method is that it's hard to reconstruct the entire 3d structure of bigger plants like trees so a lot of the root drawings on the site don’t accurately show how deep they go. It’s much easier with small plants where the researcher can control the soil us…

I had assumed they had grown the plant between two vertical, parallel panes of glass.

Some of the images (at least one I saw of a tree) had section drawings both from the side and the top, so no!

I thought it'd be about Lie groups! https://en.wikipedia.org/wiki/Root_system

The context of HN is interesting. We see the word “root” and immediately assume it has to do with a filesystem or math… but not actual, physical roots haha

I was convinced it was about trees, just not ... that kind of tree!
