Question

Identify the model that best represents the plasma membrane of a hypothetical cell that exists in a nonaqueous environment and whose eytosol is similar to that of an animal cell. Provide TWO pieces of reasoning to support your identification.

Answer 1

The models are missing in the question. The models along with the question is provided in the attachment below.

The answer is : Model A represents the Plasma membrane.

Step-by-step explanation:

According to the question, model A represents the plasma membrane. The reasons are :

(a). In the model A, the bilayers consists of two leaflets of the amphipathic lipid molecules. Here the polar head groups is in contact with the intra cellular or the extra cellular non aqueous phase, where the non polar tails are facing each other constituting the hydrophobic interior of the membrane.

(b). Lipid are not rigid as well as static structure. In the lipid bilayer, the lipid molecule are able to rotate around their axis freely and diffuse laterally with each leaflet.

(c). The plasma membrane acts as the selective plasma membrane.
