FUTURE GOALS. "The growing shoot and root must retain their model of the predicted future resources for several days to oversee these phenotypic changes and until the new leaves and roots start to transport resources to the rest of the plant." http://link.springer.com/article/10.1007/s00114-005-0014-9 View in LinkedIn

PLANT SOUNDS. "That plants produce sound waves has been known for some time. Specifically, plants emit sound waves at the lower end of the audio range within 10–240 Hz (audio acoustic emissions) as well as ultrasonic acoustic emissions (UAE) ranging from 20 to 300kHz. Over the last 45 years, these acoustic emissions (and particularly the UAE) have been measured and described several times." https://lnkd.in/dd33rp7 View in LinkedIn

CAREFUL INVESTMENT PLANNING. "Leaves do not transport fixed carbon until nearly mature; instead they act as a speculative drain on the limited supplies of root minerals and water. Likewise roots only sequester minerals in their mature regions. Inaccurate speculation, that is poor decision-making, can waste valuable resources and short shrift can be expected in the Darwinian struggle." http://link.springer.com/article/10.1007/s00114-005-0014-9 View in LinkedIn

WATER PIPES. "Another experiment, done in Mancuso’s lab and not yet published, found that plant roots would seek out a buried pipe through which water was flowing even if the exterior of the pipe was dry, which suggested that plants somehow “hear” the sound of flowing water." https://lnkd.in/dvFaNgd View in LinkedIn

RESOURCE GRADIENTS. "It is growth along gradients of resources that lead both root and shoot to eventually meet rich pockets. Exploratory shoots will grow along light gradients to the more intense regions and roots will grow along humidity and mineral gradients. Information transduced by resource sensors thus directs behavioral responses that increase the probability of attainment of richer sources of food in the near future." http://link.springer.com/article/10.1007/s00114-005-0014-9 View in LinkedIn

PREDATOR TRIGGERS. "Heidi Appel, a chemical ecologist at the University of Missouri, found that, when she played a recording of a caterpillar chomping a leaf for a plant that hadn’t been touched, the sound primed the plant’s genetic machinery to produce defense chemicals." https://lnkd.in/dvFaNgd View in LinkedIn

DIVISION OF LABOR. "Many trees are constructed from long and short shoots, the long being exploratory for new light sources in a canopy of light patches, whilst short shoots carry most of the leaves and exploit light already available." http://link.springer.com/article/10.1007/s00114-005-0014-9 View in LinkedIn

PLANT ACTION POTENTIALS. "The majority of cells in different plant species are electrically active and excitable, being able to release and propagate action potentials (APs). These electrical signals even influence principal physiological processes such as photosynthesis and respiration." https://lnkd.in/eVTKbBi View in LinkedIn

"ELECTRICAL PHENOMENA in single plant cells are to a great extent very similar to those occurring in animal cells. All plant cells actively maintain an electrical cell membrane potential difference of −30 to −250 mV between the vacuole or cytosol and the external medium." https://lnkd.in/eVTKbBi View in LinkedIn
