plant magic

[Friend]

Okay so i'm a somewhat educated person and i have basic knowledge of cell biology. But i have a question for the plant experts among us.

One thing that's always stumped me is how seeds know which way to grow to get to the surface of the ground. What's going on in the cells of an emerging taproot that signals which way is up or down??

Now if we can figure out how gravity works hehehe

when the seed pops underground, a very small goblin comes out the seed, he has this little goblin crane that he uses to get the little sprout out of the ground.

there u go, another case solved.

later

geotropism.

no, I don't think it's magic. I think it just is.

what I wonder here is about the need to categorise and inventorise EVERYTHING ... to draw everything into our left brain understandings. not that we shouldn't do this sometimes ... if we didn't we wouldn't yet have worked out the seasons ... but I wonder here what's the need to know?

cheers from an elder ...

i'm just someone who has always been scientifically curious, its just my nature to try to find out how the natural world works.

Gravitropism/geotropism is definitely the answer to my question but i'm trying to get more detail... like if there's a chemical compound in the plant's cells that forms some kind of gradient in the direction of gravity that transmits a signal to the sprout.

Why do i want to know this? No clue, it's just how i am.

It might be an issue in space.

nothing personal ... just an observation ... my point is: you seem to be interested in what impels seed behaviour but seem disinterested in what impels your own behaviour!

of course it's much easier to look at outside things than it is to look at things on the inside, isn't it?

IRONIC ... yes?

i think it has something to do with apples

 

[Warped1]

Yes I suppose so walt lol

plants know which way to grow because the ones that didnt never lived to reproduce

that's a valid take on the subject... however i don't think that my tendency to wonder about such things is indicative of some sort of character flaw....

i saw it exsplaind on tv.once. in the root there is a sack full of fluid, and one grain of sand. the grain orients down ward. and gives the plant its bearing

character flaw?!

not a character flaw ... absolutely nothing personal Friend (and I 'd like to be). simply an observation of human behaviour. we are far more interested in what's outside us than we are in what's going on INSIDE ourselves.

like the hardest thing for us to do is be honest about our motivations ... why did we do this or that?

but we don't like doing the hard stuff even tho knowing ourselves better makes life easier in the long run ... well, if not easier there is a certain detachment and peace with it ... CHEERS
