The amount of light required depends on the species; overall, air plants with silver dusting and stiff foliage will require more sunlight than air plants with softer foliage. They generally need a strong light. In summer outside, however, they prefer the light shade of a tree at the hottest hours.
After three hours in darkness it was seen that the vascular tissue was resupplied with liquid water. This was possible because in darkness the stomates of the plant are closed and transpiration no longer occurs. When transpiration is halted the cavitation bubbles are destroyed by the pressure generated by the roots.
Phytoremediation technologies use living plants to clean up soil, air and water contaminated with hazardous contaminants. [1] It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless". [2]
Air plants are epiphytes, meaning they anchor to a host plant by their roots. They do not need soil to grow, absorbing moisture and nutrients through little scale-like structures, called trichomes ...
Botanists have calculated that there are about 600 square inches [3,871 cm 2] of surface inside a leaf for every cubic inch [16.38 cm 3] of its bulk and that a large elm tree has in all some 15 million leaves within an area, if spread out whole, of nearly 10 acres [4.05 ha] or, if unfolded into the sum total of air-breathing light-absorbing ...
Heliotropism, a form of tropism, is the diurnal or seasonal motion of plant parts (flowers or leaves) in response to the direction of the Sun. The habit of some plants to move in the direction of the Sun, a form of tropism, was already known by the Ancient Greeks. They named one of those plants after that property Heliotropium, meaning "sun turn".

Plant perception is the ability of plants to sense and respond to the environment by adjusting their morphology and physiology. [1] Botanical research has revealed that plants are capable of reacting to a broad range of stimuli, including chemicals, gravity, light, moisture, infections, temperature, oxygen and carbon dioxide concentrations, parasite infestation, disease, physical disruption ...
