WebChapter 49: Minerals 577. Section VIII: Minerals, Bones, and Joints Chloride. Function Chloride is the chief anion of the extracellular fluid and plays a role in maintaining osmotic pressure and water content (extra cellular volume) of the circulation. As one of the strong ions of the blood, it plays a key role in acid–base balance of the body. In plants and animals, mineral absorption, also called mineral uptake is the way in which minerals enter the cellular material, typically following the same pathway as water. In plants, the entrance portal for mineral uptake is usually through the roots. Some mineral ions diffuse in-between the cells. In contrast to water, some minerals are actively taken up by plant cells. Mineral nutrient concentration in roots may be 10,000 times more than in surrounding soil.

Web• Active uptake of mineral ions in the roots causes absorption of water by osmosis Plants take up water and mineral ions from the soil via their roots and thus need a maximal surface area to optimise this uptake Some plants have a fibrous, highly branching root system which increases the surface area available for absorption WebUnlike water, all minerals cannot be passively absorbed by the roots. Therefore, most minerals must enter the root by active absorption. After the ions have reached xylem through active or passive uptake, or a combination of the two, these ions are transported to different parts of the plant.

WebCorrect option is C) The mineral salts are absorbed into the symplasm i.e. cytoplasm of root cells. There are special specific mineral transporters present in the plasma membrane of cells, which absorb the minerals from soil solution by transporting them across the membrane from soil solution to the cytoplasm of root cells.
