Same way as everything else: distance travelled x force exerted.
If you want an actual answer, you need to specify what you actually mean. How do they collect energy, how do they grow or whatever?

I meant like how do they do stuff like get water from the ground, exactly? It's not like they have arms inside their trunk, so how does that even work? And how does transpiration work? My Earth Science teacher explained what it is but not how it works which left me confused. And also do they actually feel stuff like pain? Mythbusters did it and allegedly plants feel emotions but I'm not buying it. Makes no sense. And how do they convert water and light and nutrients into energy? Does light absorbed by plants just morph into a bunch of plant power or something? I know so little about plants, wow.

Hey sprout. Have any two interguild staff members met in real life? I'm not talking about former staff members such as Haily.

Well, Bmwsu is my cousin, so now that he's staff I just need to become staff

Can you really survive a nuclear explosion by hiding in a fridge?

The get water from the ground through osmosis I think. Fresh water has a lower entropic value than salt water. The water inside plants and trees have all these nutrients dissolved in them. So they have a membrane through which water can pass but not nutrients. Because of statistical physics the water will seep into the tree to equalize the nutrient levels at both sides a bit. I think the roots can also absorb nutrients, which will probably work through similar mechanics, but I'm not sure about that.
Again, statistical mechanics. Water vapor has a higher enthalpy than liquid water. Enthalpy is a form of energy. So to cross over from liquid to vapor, the water needs to draw energy from somewhere. This is generally the heat of the surface. Water evaporates, surface cools down. Simple.
Plants can feel stress. My oldest sister has done a research in this for her bachelor. While they don't know emotions like we do, plants do release stress hormones when they are in danger or are being harmed. This stress is not healthy for the plants.
Chloroplasts (the green stuff in plant cells which they use to absorb sunlight and convert it into energy) are basically solar cells. They absorb sunlight, which allows electrons to go into a higher energy state. Imagine a ball in a pit. If you don't do anything to it, it will just remain at the bottom. But if you introduce energy into it by giving it a push, it will go higher and if given enough energy might even escape the pit altogether. If an electron gets enough energy, it will escape from its bonding atom. The chloroplast can now use this energetic electron to bind CO2 and water together into C6H12O6 and oxygen. I think this is similar to reverse oxidation reactions, like how you charge up a battery by running current through it, but I'm not entirely sure on that.



Not that I know of.



That is about as likely as hitching a ride between two continents by holding on to the top of a submarine.

Jell is correct about osmosis/diffusion allowing them to get the water. Transpiration occurs because plants open up their stomata's (pl stoma I think in reality) in order to allow oxygen in and out, which is used in respiration and is produced in photosynthesis, to diffuse in and to let carbon dioxide in and out of the plant which is used in photosynthesis and produced in respiration. However, in doing this water vapour is able to diffuse out of the leaf, resulting in unwanted water loss for the plant. Basically plants suck

How many countries are there, in your opinion?

hey sprout. What language should I learn other than french?

@Neezles And HB

Chinese, or maybe indian

What is one area that you have little to no knowledge in, yet want to learn more about?

Chinese:

Indian:


Now tell me WHAT do you mean by Chinese and Indian?

He means Unclassified

ALL OF IT!

@Atvelonis: I hear the number 195 (the 193 UN members + Vatican City and Palestine) pop up a lot. I think this is a reasonable number.

@Neezles and HB (which one, really?): Personally, I wouldn't even bother with French. Most of them know English anyway and the ones who don't are either too dumb or too stuck up to be worth talking to.
My favourite language has to be Latin. It can't be replaced by English and has really interesting texts.

@Bmwsu: I don't know. If I want to know more about something, I look it up on Wikipedia. So there aren't really much of such subjects that I don't know anything about but still want to.

French people are worse at English than most other western countries but still not bad enough to justify learning French voluntarily for functional reasons

This is neezles. I'm not going to learn a dead language and I have to learn French in school cause I live in Canada. At least for now. It might be different in high school but idk.

How many hairs does a regular person have on their body on a given moment?

As a whole, do you think xkcd is decreasing in quality? Not to go full hipster, but more often than not to me these days it just seems like his nerd soapbox to wax lyrical observations about how wacky/fun science or technology is rather than make actual strips that are actually funny like they seemed to be more often in the past. Occasionally one comes along that still kills me, and as a whole I still think it's worth reading, but I like it less than I used to. Not to mention the What Ifs seem to get updated more erratically. Do you see any truth in what I said, or do you just think he is evolving as an artist?  

Yeah, it has definitely decreased in quality. It is still good, though.

1 in 30 xkcd comics were ever good, people just like to forget the amount of terrible, terrible comics

I still enjoy xkcd as much as ever. If there's any decrease in quality I've yet to notice.  

I've not been following them in a long while by now. I don't recall any decrease of amount of laughter, though.

Hey sprout, what should I do if I want to understand xkcd comics.

Go to college and major in either physics, mathematics or computer science. That should help you understand most of it.
