Because of their lack of particular xeromorphic adaptations, when they are exposed to extreme conditions they lose water rapidly, and are not tolerant of drought. Mesophytes are intermediate in water use and needs. These plants are found in average conditions of temperature and moisture and grow in soil that has no water logging.
A xerophyte (from Ancient Greek ξηρός (xērós) ' dry ' and φυτόν (phutón) ' plant ') is a species of plant that has adaptations to survive in an environment with little liquid water. Examples of xerophytes include cacti, pineapple and some gymnosperm plants.
Phylogenetic studies have shown that carnivory in plants is a common adaptation in habitats with abundant sunlight and water but scarce nutrients. [43] Carnivory has evolved independently six times in the angiosperms based on extant species, with likely many more carnivorous plant lineages now extinct. [59]
The Private Life of Plants is a BBC nature documentary series written and presented by David Attenborough, first shown in the United Kingdom from 11 January 1995. A study of the growth, movement, reproduction and survival of plants , it was the second of Attenborough's specialised surveys following his major trilogy that began with Life on Earth .
The main Early Carboniferous plants were the Equisetales (Horse-tails), Sphenophyllales (scrambling plants), Lycopodiales (Club mosses), Lepidodendrales (arborescent clubmosses or scale trees), Filicales (Ferns), Medullosales (previously included in the "seed ferns", an artificial assemblage of a number of early gymnosperm groups) and the ...
The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common. [5] [6] [7] Aquatic plants only thrive in water or in soil that is frequently saturated, and are therefore a common component of swamps and marshlands. [8]
Land plants evolved from a group of freshwater green algae, perhaps as early as 850 mya, [3] but algae-like plants might have evolved as early as 1 billion years ago. [2] The closest living relatives of land plants are the charophytes, specifically Charales; if modern Charales are similar to the distant ancestors they share with land plants, this means that the land plants evolved from a ...
Heliophytes or sunstroke plants are adapted to a habitat with a very intensive insolation by their structure and metabolism. Examples are mullein, ling, thyme and soft velcro, white clover, and most roses. They are common in open terrain, rocks, meadows, as well as at the mountain pastures and grasslands and other long sunny exposures. [1] [2]
