> How are plants, with no advanced nervous system, able to gather information about their environment to guide their behavior, planning and flexibly executing movement? Sound, maybe. Or chemoreception. Possibly even eye-like structures.
'eye-like structures'?!
https://doi.org/10.1016/j.tplants.2016.07.008 https://doi.org/10.1016/j.tplants.2016.07.008:
Although plants are sessile organisms, almost all of their organs move in space and thus require plant-specific senses to find their proper place with respect to their neighbours. Here we discuss recent studies suggesting that plants are able to sense shapes and colours via plant-specific ocelli.
Cannot access the study but this sounds fascinating!

- diggan 6y agoNot sure if others have the same problem, but where I live (Spain), sci-hub.se is unavailable. sci-hub.st still works though, so mirror is here: https://sci-hub.st/https://www.cell.com/trends/plant-science/fulltext/S1360-1385(16)30093-0 https://sci-hub.st/https://www.cell.com/trends/plant-science...
- jraph 6y agosci-hub.se works here (France), however sci-hub.tw does not load anymore. I'll say that if neither sci-hub.se nor sci-hub.st load on your connection, they are probably blocked for legal reasons at your place and you should of course neither attempt to switch to another DNS server nor put the following text in your /etc/hosts file to make them resolve: 186.2.163.219 sci-hub.se 186.2.163.201 sci-hub.st See https://news.ycombinator.com/item?id=20606718 https://news.ycombinator.com/item?id=20606718 for more information.
- Gys 6y agoWow, thanks!
- generalizations 6y agoNo prob. Scihub opens a whole new world.
- vmception 6y agoI always wished Scihub had a browse feature It relies on knowing what paywall I want to circumvent with some paper's ID When really I just want to browse I'm not in academia and I feel like everyone salivating over Scihub don't realize this use case, because they already know what publications they don't have access to Since its almost 10 years after Scihub launched, is there a chrome extension or other wrapper for to make browsing easy on it, or some app that indexes newly released papers from a variety of journals and auto generates the scihub link equivalent?
- kevinmchugh 6y agoI use Google scholar to find interesting papers and scihub to read them.
- generalizations 6y agoI had the same response when I first got started with it. Thing is, that's not what it was designed for. There's tons of other resources to use when actually researching; scihub just makes sure that what you find, you can access.
- vmception 6y agoI’ve seen more contrived services that combine two or three things for more convenience Would be surprising for someone not to do this with scihub yet
- Siira 6y agoI think you can browse the papers via the libgen interface: http://gen.lib.rus.ec/ http://gen.lib.rus.ec/

- dalbasal 6y agoConsidering that they photosynthesize, photosensitivity doesn't seem like that much of a leap.
- slavik81 6y agoIf you have photosynthesis, you already have photosensitivity. The process of photosynthesis will cause chemical gradients in the reaction's inputs and outputs (and those of secondary reactions) that indicate where the plant senses light. Exactly how those are leveraged, I don't know, but based on hanging out with folks who study this for a few years, I'm going to bet it's very complicated and somehow involves auxin.

- pvaldes 6y agoPlant physiology is a branch of biology that studies this, and have developed clear and reasonable explanations. Some that don't involve having parts of animals scattered in plants.
