  • At the same time, plants need to maintain a continuous column of water from root to leaf. (mongabay.com)
  • Partially closed stomata release less water, and therefore do less cooling. (iflscience.com)
  • The JAZ2 targets MYC2, MYC3 and MYC4 directly regulate the expression of ANAC19, ANAC55 and ANAC72 to modulate stomata aperture. (nih.gov)

  • Some of the plants use the so-called NAD-malate enzyme for this purpose. (uni-bonn.de)
  • A water-saving mode of photosynthesis whereby CARBON DIOXIDE (CO2) taken up during the nocturnal opening of stomata (STOMATA, PLANT) is fixed to produce malate, which is accumulated in VACUOLES overnight as malic acid and subsequently decarboxylated during the day with the resulting CO2 produced being re-fixed by RUBISCO and re-assimilated through the REDUCTIVE PENTOSE PHOSPHATE CYCLE.

  • Observing stomata on a leaf using a microscope. (kolblabs.com)
  • A watertight covering called the cuticle, which reduces water loss, made it possible for plants to live in drier habitats. (slideserve.com)
  • Plants in deserts have only a few stomata to reduce water loss. (proprofs.com)
  • What do you call the process of water loss in plants? (proprofs.com)
  • They account for around 80 to 90% of the total water loss from the plants. (toppr.com)
  • Stomata are key regulators of plant water loss, photosynthesis, and body temperature. (uwosh.edu)
  • Closely observing plant life reveals sometimes surprising connections to our own existences. (gardenguides.com)
  • The paper reveals that a collaboration between plant biologists and climate scientists found something frightening. (iflscience.com)
  • They are responsible for gas exchange in plants, allowing carbon dioxide to enter the leaf for photosynthesis and oxygen to exit. (proprofs.com)
  • CAM photosynthesis is found mostly in plants in arid areas, but it is also found in aquatic plants and orchids. (bvsalud.org)
  • This experiment helps in understanding the structure and function of stomata, which are crucial for plant survival. (kolblabs.com)
  • Professor Morris said that next the researchers will study grass stomata which have a different shape and are likely to have a different underlying mechanism. (earth.com)
  • Latest climate and biosphere modelling suggests that the length of time carbon remains in vegetation during the global carbon cycle - known as 'residence time' - is the key "uncertainty" in predicting how Earth's terrestrial plant life - and consequently almost all life - will respond to higher CO2 levels and global warming, say researchers. (wattsupwiththat.com)
  • Initially, higher atmospheric CO2 will encourage plant growth as more CO2 stimulates photosynthesis, say researchers. (wattsupwiththat.com)
  • The researchers say that, in light of the new evidence, scientific focus must shift away from productivity outputs - the generation of biological material - and towards the "mechanistic levels" of vegetation function, such as how plant populations interact and how different types of photosyntheses will react to temperature escalation. (wattsupwiththat.com)
  • That is the finding of a multidisciplinary team of researchers, who said the results may yield insights into the abilities of crop plants - such as tomato and soybean - to withstand additional stressors, like climate change. (uncommondescent.com)
  • This process is essential for plants as it helps to transport nutrients and minerals, cool the plant, and maintain turgidity. (proprofs.com)
  • Its primary function is storing water and nutrients and transporting them throughout the plant. (visiblebody.com)
