  • Tell me you don’t communicate science often without saying it. Know the audience is rule 1.

    But ok, ‘tell’ is useful anthropormophism to get an idea across. Sensing though? In what way is reacting to a stimuli not sensing? It is the word scientific papers use. What would you say instead?


  • A little, the stretching house plant demonstrates how plants can sense the direction light is coming from. They can also sense qualities of light. They can tell if light is filtered through other leaves, for instance. I would speculate that refected light also has a unique color (wavelength) distribution that a plant could sense and respond to



  • It isn’t common, and explode is an exaggeration for what I have seen - just cracked bark (though the crack was probably abrupt and loud). Montana gets some every now and again, so I am guessing at least some parts of Alberta do too. Nobody has made a big deal about it in the past outside of folks interested in trees. This is some weird media hype.




  • Having worked growing native plants for restoration efforts, I can say that this is 100% true. Our focus was on getting plants that will survive without any extra help after being put in the ground, so no fertilizer and limited water. A scraggly leaved plant with good roots would make it where something with lots of soft new growth would get eaten.








  • Yeah, it usually used to indicate unwanted flowering, but in lettuces (and to a lesser extent, basil) it indicates the beginning of the flowering attempt by the plant. Most people will cull their lettuce after it bolts (stem starts to elongate into an inflorescence), but way before there are any open flowers or even buds.

    Broccoli is weird though. We want it to bolt, but not really flower. That’s an odd thing for most plants.
