The earliest recorded observation of this behavior in plants dates back to 324 BC when Androsthenes of Thasos, a companion to Alexander the Great, noted the opening and closing of tamarind tree leaves from day to night. [15] Carl Linnaeus (1729) proposed that this was the plants sleeping, but this idea has been widely contested.
At night, transpiration usually does not occur, because most plants have their stomata closed. When there is a high soil moisture level, water will enter plant roots, because the water potential of the roots is lower than in the soil solution. The water will accumulate in the plant, creating a slight root pressure.
Mold spores are often spherical or ovoid single cells, but can be multicellular and variously shaped. Spores may cling to clothing or fur; some are able to survive extremes of temperature and pressure. Although molds can grow on dead organic matter everywhere in nature, their presence is visible to the unaided eye only when they form large ...
Outdoors, molds play an important role in breaking down organic matter like decaying leaves, but inside, mold can spoil foods or grow on damp surfaces and should be avoided, according to the EPA ...
A variety of other mold species, such as Penicillium or Aspergillus, may appear to grow on non-cellulosic surfaces but are actually growing on the biofilm that adheres to these surfaces. Glass, plastic, and concrete provide no food for organic growth and as such cannot support mold or mildew growth alone without biofilm present.
Mold illness isn’t easy to define, and the path from home mold growth to debilitating chronic health symptoms is complicated. But often the story starts like this: Moisture in a home can cause ...
Cladosporium species are present in the human mycobiome but are rarely pathogenic to humans. They have been reported to cause infections of the skin and toenails as well as sinuses and lungs, with more common symptoms including nasal congestion, sneezing, coughing, and itchy eyes. [8]
Scrolling on social media is also a way to "disassociate" and give the brain a rest after a long day, Bobinet said. This is an "avoidance behavior," which the habenula controls.
