The mechanisms of wind tolerance are still poorly understood. Wind not only causes mechanical stress, but also makes the plant colder and dryer. Plants may evolutionally adapt to wind by becoming smaller (to avoid wind) or bigger (to resist the wind). Physiologically, the mechanical force also causes a cascade of signals in the living plant.

Some plants can store water in their root structures, trunk structures, stems, and leaves. Water storage in swollen parts of the plant is known as succulence. A swollen trunk or root at the ground level of a plant is called a caudex and plants with swollen bases are called caudiciforms.
Light is the food of plants, i.e. the form of energy that plants use to build themselves and reproduce. The organs harvesting light in plants are leaves and the process through which light is converted into biomass is photosynthesis. The response of photosynthesis to light is called light response curve of net photosynthesis . The shape is ...
A plant which completes its life cycle (i.e. germinates, reproduces, and dies) within two years or growing seasons. Biennial plants usually form a basal rosette of leaves in the first year and then flower and fruit in the second year. bifid Forked; cut in two for about half its length. Compare trifid. bifoliate
Tiny hair-like structures called trichomes on the surface of leaves also can inhibit water loss by creating a high humidity environment at the surface of leaves. These are some examples of the adaptations of plants for the conservation of water that may be found on many xerophytes. Light supply

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".
“We saw damage to plants this summer that had never showed heat stress before,” Schilling said. Sunburned leaves of a mock orange shrub on Aug. 23. Brown patches show where the tissue was damaged.
