Give an account of nutrient uptake mechanism in plants.
Answers
The nutrient uptake refers to the process of nutrient movement from an external environment into a plant. It is one of the fundamental demonstrations of plant’s life which involves especially a qualitative change where an abiotic material becomes a component of a cell capable of further assimilation processes, resulting in production of new mass. Plants receive mostly carbon and oxygen in a form of CO2 from air and partly hydrogen. These nutrients enter a plant in a molecular form. Thanks to leaves, stems, and eventually generative organs (klasů, lat, crops) most plants can also receive other nutrients, such as N, P, K, Ca, Mg, mikroelements, etc., mostly in a form of soluble salts of certain concentration. Such way of nutrition is marked as foliar (folic) nutrition. Besides, plants receive all nutrients and water by roots.
