In biology, homeostasis (British also homoeostasis; / h ... certain plants may be able to grow better and thus act to remove more carbon dioxide from the atmosphere.
Guard cells perceive and process environmental and endogenous stimuli such as light, humidity, CO 2 concentration, temperature, drought, and plant hormones to trigger cellular responses resulting in stomatal opening or closure. These signal transduction pathways determine for example how quickly a plant will lose water during a drought period.
Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated.
Plant communication encompasses communication using volatile organic compounds, electrical signaling, and common mycorrhizal networks between plants and a host of other organisms such as soil microbes, [2] other plants [3] (of the same or other species), animals, [4] insects, [5] and fungi. [6]
Homoiohydry is the capacity of plants to regulate, or achieve homeostasis of, cell and tissue water content. Homoiohydry evolved in land plants to a lesser or greater degree during their transition to land more than 500 million years ago, and is most highly developed in the vascular plants.
Potassium plays a vital role in the plants growth, reproduction, [9] immunity, ion homeostasis, and osmosis, which ensures the plants survival. It is the highest cationic molecule within the plant, accounting for 10% of the plants dry weight, which makes its uptake into the plant important. [8]
Like the general biological notion of homeostasis, elemental homeostasis refers to the maintenance of elemental composition within some biologically ordered range. Photoautotrophic organisms, such as algae and vascular plants , can exhibit a very wide range of physiological plasticity in elemental composition and thus have relatively weak ...
A germination rate experiment. Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. [1]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 ...
