Bioconcentration - Wikipedia


Bioconcentration is the accumulation of a chemical in or on an organism when the source of chemical is solely water. Bioconcentration is a term that was created for use in the field of aquatic toxicology. Bioconcentration can also be defined as the process by which a chemical concentration in an aquatic organism exceeds that in water as a result of exposure to a waterborne chemical.

Photosynthesis - Wikipedia


Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek φῶς, phōs, "light", and σύνθεσις ...

Systems of Photosynthesis - hyperphysics.phy-astr.gsu.edu


Plants which use only the Calvin cycle for fixing the carbon dioxide from the air are known as C3 plants. In the first step of the cycle CO 2 reacts with RuBP to produce two 3-carbon molecules of 3-phosphoglyceric acid (3-PGA). This is the origin of the designation C3 or C 3 in the literature for the cycle and for the plants that use this cycle.

Micronutrients: Functions, Sources and Application Methods


Plants store iron as ferritin, a protein that encapsulates ferric iron. Under aerobic soil conditions, iron is largely insoluble as a constituent of oxides and hydroxides. Ferric iron tends to be tied up in organic chelates. Hence, the concentration of free iron in the soil solution is exceedingly low in many soils. Plants have mechanisms to

Archive - California Agriculture


California and the rest of the world are experiencing major changes in the availability of water and the concentration of atmospheric carbon dioxide (CO 2).Water and CO 2 — along with energy from the sun — are the inputs to photosynthesis, the basis of plant growth and food production. Elevated CO 2 can influence the water use efficiency and yield of crop plants.

Osmosis in plant cells - Pass My Exams


Water will now pass from this area of high concentration to the next cell which has a low water concentration by osmosis. In this way water continues to move along the cells of the root up the xylem to the leaf. all the time water is moving to areas of lower water concentration. As water enters plant cells it makes the cell swell up.

In this section, we examine two types of transport phenomena that, at first glance, may seem unrelated: the regulation of cell volume in both plant and animal cells, and the bulk flow of water (the movement of water containing dissolved solutes) across one or more layers of cells. In humans, for example, water moves from the blood filtrate that will form urine across a layer of epithelial ...
