Which of the following statements describes the function of plasma membranes? I. define boundaries of the cell and its organelles and act as permeability barriers II. contains pigments that captures light energy. III. possess transport proteins that regulate the movement of substances into and out of the cell. IV. allows the entry and exit of cell organelles. V. provide mechanisms for cell-to-cell contact, adhesion, and communicationI, III, IV, VI, II, III, IVI and IIII, III, V

what is plasma membrane in detail, what is history of plasma membrane and functions of plasma membrane

What are the functions of the cell membrane?Multiple select question.It is the site of signal transduction.It is the site of protein synthesis.It is a selectively permeable barrier.

The plasma membrane is an essential part of the cell. It surrounds the cell and has a unique chemical combination that allows for the transport of molecules into and out of the cell.Figure 2. The eukaryotic plasma membrane is a phospholipid bilayer with proteins and cholesterol embedded in it. by OpenStax (CC BY-SA 4.0)Which of the following statements describes the chemical composition of the plasma membrane and the permeability of the membrane?Elimination ToolSelect one answerAThe plasma membrane is hydrophilic on the outside layers and hydrophobic in the inside layers. The plasma membrane is permeable.BThe plasma membrane is hydrophobic on the outside layers and hydrophilic in the inside layers. The plasma membrane is permeable.CThe plasma membrane is hydrophobic on the outside layers and hydrophilic in the inside layers. The plasma membrane is semi-permeable.DThe plasma membrane is hydrophilic on the outside layers and hydrophobic in the inside layers. The plasma membrane is semi-permeable.

Which is a function of the plasma membrane?regulate traffic of chemicals in and out of the cellregulate production of lipids in the cellregulate production of proteins in the cellregulate transport of DNA in and out of the nucleus
