Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. [1]A germination rate experiment. Plant physiologists study fundamental processes of plants, such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed ...
The APG IV system of flowering plant classification is the fourth version of a modern, mostly molecular -based, system of plant taxonomy for flowering plants (angiosperms) being developed by the Angiosperm Phylogeny Group (APG). It was published in 2016, seven years after its predecessor the APG III system was published in 2009, and 18 years ...
Grain, fruit, and vegetables are basic human foods and have been domesticated for millennia. People use plants for many purposes, such as building materials, ornaments, writing materials, and, in great variety, for medicines. The scientific study of plants is known as botany, a branch of biology .
Setaria palmifolia is a species of grass known by the common names palmgrass, [ 2] highland pitpit, hailans pitpit, short pitpit, broadleaved bristlegrass, and knotroot. It is native to temperate and tropical Asia. [ 3] It is known elsewhere as an introduced, and often invasive, species, including in Australia, New Zealand, many Pacific Islands ...
Phacaceae. Genus: Phacus. Dujardin, 1841. Phacus is a genus of unicellular excavates, of the phylum Euglenozoa (also known as Euglenophyta), characterized by its flat, leaf-shaped structure, and rigid cytoskeleton known as a pellicle. These eukaryotes are mostly green in colour, and have a single flagellum that extends the length of their body.
Archidendron pauciflorum, commonly known as djenkol, jengkol or jering, is a species of flowering tree in the pea family, Fabaceae. It is native to Southeast Asia, where the seeds are also a popular dish. [ 2] They are mainly consumed in Indonesia, Thailand, Myanmar, and Vietnam, prepared by frying, boiling, or roasting, and eaten raw. [ 3]
A xerophyte (from Greek ξηρός xeros 'dry' + φυτόν phuton '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. The morphology and physiology of xerophytes are adapted to conserve water during dry periods.
In biology, metamerism is the phenomenon of having a linear series of body segments fundamentally similar in structure, though not all such structures are entirely alike in any single life form because some of them perform special functions. [ 1] In animals, metameric segments are referred to as somites or metameres.
