The directed movement of silicates from outside of a cell, across the plasma membrane and into the cytosol. Silicates are the salts of silicic acids, and are usually composed of silicon and oxygen (Si

The directed movement of urea into, out of or within the cell. Urea is the water-soluble compound H2N-CO-NH2.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus reflecting the presence, absence, or concentration of boron-containing substances.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a boron-containing substance stimulus.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a boron-containing substance stimulus.

The directed movement of arsenite into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

The process in which borate is transported across a membrane. Borate is the anion (BO3)3-; boron is a group 13 element, with properties which are borderline between metals and non-metals.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an arsenic stimulus from compounds containing arsenic, including arsenates, arsenites, and arsenides.

The directed movement of borate into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Borate is the anion (BO3)3-; boron is a group 13 element, with properties which are borderline between metals and non-metals.

The directed movement of borate into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Borate is the anion (BO3)3-; boron is a group 13 element, with properties which are borderline between metals and non-metals.

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

Region of plant cell wall specialised to act as a seal to prevent back leakage of secreted material (analogous to tight junction between epithelial cells). Found particularly where root parenchymal cells secrete solutes into xylem vessels. The barrier is composed of suberin; a fatty substance, containing long chain fatty acids and fatty esters, also found in the cell walls of cork cells (phellem) in higher plants.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The portion of the plasma membrane at the lateral side of the cell. In epithelial cells, lateral plasma membranes are on the sides of cells which lie at the interface of adjacent cells.
