Mineral salts are absorbed from the soil solution in the form of ions. They are chiefly absorbed through the meristematic regions of the roots near the tips. However, some mineral salts may also be absorbed at other locations on the root surface or over the entire root surface including zone of elongation and root hairs that depends upon the high availability of such minerals around them and/or strong tissue demand at such locations. ADVERTISEMENTS: Plasma membrane of the root cells is not permeable to all the ions. It is now known that during passive absorption, the mineral salts may diffuse through cell membranes directly through lipid bilayer but mainly through trans-membrane ion-selective protein channels or trans-membrane carrier proteins. Carrier or channel mediated passive transport of mineral salts across the membrane is also called as facilitated diffusion (Fig. ).
The title first covers the history of mineral salt absorption in plants, and then proceeds to tackling the experimental materials and methods. Next, the selection discusses the mechanisms of ion transport. Chapter 4 deals with the factors affecting salt absorption, while Chapter 5 talks about salt absorption and metabolisms. In the sixth chapter, the text covers the structural aspects of salt absorption in cells. The seventh chapter discusses the salts relations of vascular plants. The selection also talks about the soil as a source of mineral salts, along with salt tolerance

Mineral salts are taken up in soluble form. When mineral salts dissolve in water they separate into particles called ions. Some of the ions travel by diffusion into the root; others are absorbed by active transport . Some species of climbing plants develop holdfast roots which help to support the vines on trees, walls, and rocks. By forcing their way into minute pores and crevices, they hold the plant firmly in place.
Formed in 2009 by the merger of the Biosciences Federation and the Institute of Biology, the society has around 18,000 individual members, and more than 100 member organisations

Biology quiz with answers. mineral salts are taken up due to diffusion because of the concentration gradient between the mineral ions in sap and those in soil solution. active transport involves energy in form of ATP due to respiration which forces mineral salts through a plant against a concentration gradient. water moves by osmosis through a semi-permeable membrane of root hairs and between cells of stem. plants require mineral salts for metabolism and proper functioning of their bodies. mineral salts are taken up from the soil into the root hairs in form of solution by active. transport which requires energy. active transport involves substances called carriers taken up together with water and are then carried to the stems and leaves.
