  2. Drought tolerance - Wikipedia

    en.wikipedia.org/wiki/Drought_tolerance

    In botany, drought tolerance is the ability by which a plant maintains its biomass production during arid or drought conditions. [1] [2] [3] Some plants are naturally adapted to dry conditions, surviving with protection mechanisms such as desiccation tolerance, detoxification, or repair of xylem embolism. [3]

  3. Plant physiology - Wikipedia

    en.wikipedia.org/wiki/Plant_physiology

    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 ...

  4. Crassulacean acid metabolism - Wikipedia

    en.wikipedia.org/wiki/Crassulacean_acid_metabolism

    The pineapple is an example of a CAM plant.. Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions [1] that allows a plant to photosynthesize during the day, but only exchange gases at night.

  5. Xerophyte - Wikipedia

    en.wikipedia.org/wiki/Xerophyte

    Examples of xerophytes include cacti, pineapple and some gymnosperm plants. The morphology and physiology of xerophytes are adapted to conserve water during dry periods. Some species called resurrection plants can survive long periods of extreme dryness or desiccation of their tissues , during which their metabolic activity may effectively shut ...

  6. Dry matter - Wikipedia

    en.wikipedia.org/wiki/Dry_matter

    Dry matter can refer to the dry portion of animal feed. A substance in the feed, such as a nutrient or toxin, can be referred to on a dry matter basis (abbreviated DMB) to show its level in the feed (e.g., ppm). Considering nutrient levels in different feeds on a dry matter basis (rather than an as-is basis) makes a comparison easier because ...

  7. Hygroscopy - Wikipedia

    en.wikipedia.org/wiki/Hygroscopy

    Movement occurs when plant tissue matures, dies and desiccates, cell walls drying, shrinking; [12] and also when humidity re-hydrates plant tissue, cell walls enlarging, expanding. [11] The direction of the resulting force depends upon the architecture of the tissue and is capable of producing bending, twisting or coiling movements.

  8. Mucilage - Wikipedia

    en.wikipedia.org/wiki/Mucilage

    A sundew with a leaf bent around a fly trapped by mucilage. Mucilage is a thick gluey substance produced by nearly all plants and some microorganisms.These microorganisms include protists which use it for their locomotion, with the direction of their movement always opposite to that of the secretion of mucilage. [1]

  9. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    In hot and dry conditions, plants close their stomata to prevent water loss. Under these conditions, CO 2 will decrease and oxygen gas , produced by the light reactions of photosynthesis, will increase, causing an increase of photorespiration by the oxygenase activity of ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) and decrease in ...
