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".
Prickles on a blackberry branch. In plant morphology, thorns, spines, and prickles, and in general spinose structures (sometimes called spinose teeth or spinose apical processes), are hard, rigid extensions or modifications of leaves, roots, stems, or buds with sharp, stiff ends, and generally serve the same function: physically defending plants against herbivory.
Now the plant can absorb more light. When the sun dries the plants, they turn white. Thanks to this special survival trick, plants without roots can absorb fog droplets as well as rainwater and thus cover their water needs. [18] More than one-third of a tropical forest's vascular plants are epiphytes which species of Tillandsia are part of.
These rapid plant movements differ from the more common, but much slower "growth-movements" of plants, called tropisms. Tropisms encompass movements that lead to physical, permanent alterations of the plant while rapid plant movements are usually reversible or occur over a shorter span of time.
Epicuticular wax is a waxy coating which covers the outer surface of the plant cuticle in land plants. It may form a whitish film or bloom on leaves, fruits and other plant organs. Chemically, it consists of hydrophobic organic compounds, mainly straight-chain aliphatic hydrocarbons with or without a variety of substituted functional groups ...

Trees can live for over 100 years, with 40-year-old trees achieving a trunk circumference of 2.7 m (9 ft) in cultivation. [ 12 ] The flowers serve as a rich source of nectar for other organisms, including fruit bats, a wide range of insect and bird species, [ 7 ] such as the scaly-breasted lorikeet ( Trichoglossus chlorolepidotus ).
The Christmas tree originally dates back to before Christmas, tying into how ancient civilizations celebrated the Winter Solstice, according to Texas A&M University. Evergreen plants were used to ...
