[Answer] The _____ is a selective barrier regulating the passage of material into and out of the cell.

Answer: The plasma membrane regulates the passage of material into and out of the cell.
The _____ is a selective barrier regulating the passage of material into and out of the cell.
Intestinal permeability is a term describing the control of material passing from inside the gastrointestinal tract through the cells lining the gut wall into the rest of the body. The intestine normally exhibits some permeability which allows nutrients to pass through the gut while also maintaining a barrier function to keep potentially harmful substances from leaving the intestine and migrating to the body more widely. In …
The endodermis is the central innermost layer of cortex in land plants.It is a cylinder of compact living cells the radial walls of which are impregnated with hydrophobic substances (Casparian strip) to restrict apoplastic flow of water to the inside. The endodermis is the boundary between the cortex and the stele.. In many seedless vascular plants the endodermis is a distinctly visible …
The cell membrane is selectively permeable and able to regulate what enters and exits the cell thus facilitating the transport of materials needed for survival. The movement of substances across the membrane can be either ” passive ” occurring without the input of cellular energy or ” active ” requiring the cell to expend energy in transporting it.
The blood–brain barrier (BBB) is a highly selective semipermeable border of endothelial cells that prevents solutes in the circulating blood from non-selectively crossing into the extracellular fluid of the central nervous system where neurons reside. The blood–brain barrier is formed by endothelial cells of the capillary wall astrocyte end-feet ensheathing the capillary and pericytes …
The lipid bilayer (or phospholipid bilayer) is a thin polar membrane made of two layers of lipid molecules.These membranes are flat sheets that form a continuous barrier around all cells.The cell membranes of almost all organisms and many viruses are made of a …
