Teaching about Water Relations in Plant Cells: An Uneasy Struggle
University students often struggle to understand the role of water in plant cells. In particular, osmosis and plasmolysis appear to be challenging topics. This study attempted to identify student difficulties (including misconceptions) concerning osmosis and plasmolysis and examined to what extent the difficulties could be revised during a plant physiology course. A questionnaire was developed ...
متن کاملEvaluation of salt-tolerant forages for sequential water reuse systems II. Plant–ion relations
Implementation of the saline drainage water reuse system proposed for the westside of the San Joaquin Valley (SJV) of California requires development of sustainable cropping systems, which incorporate useful, salt-tolerant agronomic species. Ion composition in the saline drainage effluents present in the SJV is unique, with Na, SO4 2 , Cl , Mg and Ca predominating in that order. To identify pot...
متن کاملAquaporins: highly regulated channels controlling plant water relations.
Plant growth and development are dependent on tight regulation of water movement. Water diffusion across cell membranes is facilitated by aquaporins that provide plants with the means to rapidly and reversibly modify water permeability. This is done by changing aquaporin density and activity in the membrane, including posttranslational modifications and protein interaction that act on their tra...
متن کاملAquaporins. A molecular entry into plant water relations.
Water relations are obviously crucial to the physiology of terrestrial plants, but 25 years ago most plant biologists viewed this area of research as somewhat of an oddity. Dominated by equations and unusual physical theories about liquids flowing in pipes, water relations seemed to be a field with little seeming need for the burgeoning concepts and approaches offered by molecular and cellular ...
متن کاملAssociation of water spectral indices with plant and soil water relations in contrasting wheat genotypes
Spectral reflectance indices can be used to estimate the water status of plants in a rapid, non-destructive manner. Water spectral indices were measured on wheat under a range of water-deficit conditions in field-based yield trials to establish their relationship with water relations parameters as well as available volumetric soil water (AVSW) to indicate soil water extraction patterns. Three t...
