It is a form of nastic movement, not to be confused with thermotropism, which is a directional response in plants to temperature. A common example of this is in some Rhododendron species, but thermonasty has also been observed in other plants, such as Phryma leptostachya . [ 1 ]
annual: a plant species that completes its life cycle within a single year or growing season; basal: attached close to the base (of a plant or an evolutionary tree diagram) climber: a vine that leans on, twines around or clings to other plants for vertical support; deciduous: falling seasonally, as with bark, leaves or petals
1. Illustration of electrophoresis. 2. Illustration of electrophoresis retardation. Electrophoresis is the motion of charged dispersed particles or dissolved charged molecules relative to a fluid under the influence of a spatially uniform electric field. As a rule, these are zwitterions with a positive or negative net charge. [1]
Generally, fleshy fruits can be divided into two groups based on the presence or absence of a respiratory increase at the onset of ripening. This respiratory increase—which is preceded, or accompanied, by a rise in ethylene—is called a climacteric, and there are marked differences in the development of climacteric and non-climacteric fruits.

By elongating the petiole sideways, the plant repositions its leaves away from shading plants to absorb more red light, though there is a trade off in leaf size. The leaves can also bend upwards towards potential light sources as a result of higher growth on the underside of the petiole than the top, a process called hyponasty. [ 9 ]
It has been argued that for plants that display foliar nyctinasty, it is a crucial mechanism for survival; however, most plants do not exhibit any nyctinastic movements. [1] Nyctinasty is found in a range of plant species and across xeric , mesic , and aquatic environments, suggesting that this singular behavior may serve a variety of ...
Jatropha plant Jatropha plant Jatropha plant. Jatropha is a genus of flowering plants in the spurge family, Euphorbiaceae. The name is derived from the Greek words ἰατρός (iatros), meaning "physician", and τροφή (trophe), meaning "nutrition", hence the common name physic nut. Another common name is nettlespurge. [2]
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]
