Pretty sure they mean that plants don't grow in space naturally, for obvious reasons of space being a vacuum. Unless you directly provide the carbon dioxide and water for photosynthesis and the light, it won't grow like it naturally would on Earth. In space, it requires intervention by providing the resources, but on Earth, it can grow on its own.
#324 - hammarhead (12/08/2014) [-]
Yeah, it's pretty simple. It's basic logic, really. vacuum = no gasses of any kind. many liquids, including water are also sucked away in a vacuum. Without water, carbon dioxide, or any way for them to receive adenosinetriposphates, they'd be completely unable to undergo photosynthesis.
#327 - hammarhead (12/08/2014) [-]
Alright, it's very different if we're talking about the inside of a spaceship. The inside of a space ship is no a vacuum, but a controlled environment simulating earth. In that environment, yes it's completely feasible. In fact, just regular plants could be grown in the spacecraft. It's been done. But we on the other hand are talking about the vacuum of space, which is what you asked me to explain. There is no "suction", sucked was simply the verb I used to describe what would happen to any gasses, liquids, and even some solids on the surface of a chloroplast, as the total vacuum of space would completely vaporize them, and they would fly off in all different directions. The chloroplast would then be left with no gasses or water to sustain the cycle of photosynthesis (not to mention the lack of ATP it would need to undergo it), and it would likely end up as a little shriveled microscopic ball from the intense thermal energy loss that happens when liquid is so quickly evaporated off of something. That's why choloroplasts cannot survive in the vacuum of space. Do you see what I'm saying, or am I talking with a wall?
#328 - sciencexplain (12/08/2014) [-]
Yes, I completely see what you're saying, but your choice of words was completely the wrong way to go about it. You need to use more appropriate words, so your meaning is clear or else you convey the wrong message. I did not question your intelligence, simply your knowledge of the subject to make sure you weren't confused or misunderstood in any aspect.
#329 - hammarhead (12/08/2014) [-]
Listen. No one gives a shit about words. I think you're just arguing for the sake of arguing at this point. I think they call it trying to get the last word. You asked me to tell you how chloroplasts couldn't live in space in a snarky manner. I explained patiently and kindly. Unless you've got anything else to add on the subject, hostility like this is draining and I'd rather us come to a conclusion.

>no-one gives a shit about words
I would love to see your academia work, then. Words are the most important part of presenting your knowledge. Choose the wrong words, it's not conveyed right. Sounds like you're just being angsty because you get too heated over someone from the Internet. Tone it down a bit, seriously. The "snarkiness" is all in your perception, it was not intended at all, but you can interpret as you like.
#332 - sciencexplain (12/08/2014) [-]
Seriously? No, that's not my intention. I didn't once say you were wrong (save for the "no one gives a shit about words" part, that's really wrong.) I'm just responding in an attempt to cover all the points you brought up in your comment so that they can all be resolved and you can be on your way. I'm not trying to start an argument, it's just the nature in which I've learned to respond to comments.
#335 - hammarhead (12/08/2014) [-]
Did you know that there are a few species of protists that have chloroplasts, but are also predatory? Dinoflagellates are an excellent example of this. They're very efficient creatures, and although it doesn't surprise me, it's unfortunate that there aren't many creatures like it, both auto and heterophagous. Are you at all interested in microbiology yourself?
#336 - sciencexplain (12/08/2014) [-]
Biology never was my strong subject. I was always a chemistry man myself. I enjoyed playing with sulfur hexafluoride and ammonium chromate, and burning ionised transition metals. But still, I do have an interest in some parts of biology, but microbiology never really suited me as much as some of the other fields of biology. I enjoyed anatomy and the human body, and dissecting hearts as a kid. Bacteria and amoeba never really took my fancy. It took cool stuff to keep me interested, and sitting there testing for starch in a plant leaf was nothing like decomposing carbonates thermally.

I buy ice/cold packs and use ammonium nitrate from those, and a brand of high-potassium salt, because it's got a high potassium chloride concentration. Dissolve the ammonium nitrate, strain it, boil the potassium chloride inside of it and then freeze it. It only leaves ammonium chloride waste, and when it's done, you can break down the formed crystals into a lovely flash powder. It's better than buying it online, but the problem is the salt can be hard to get in stores.

Maybe the clean one is the photoshop. Maybe that girl there has beaten the internet to erase her most emberassing moment ever. The devil's greatest achievement is making people believe he never existed.
