c) only certain membranes of the cell are selectively permeable.
d) only certain membranes are constructed from amphipathic molecules.
e) certain proteins are unique to each membrane.

The Answer is Letter E.

Explanation:

The way membranes of a eukaryotic cell vary is certain proteins are unique to each membrane.

The eukaryotic cells also contain other membrane-bound organelles such as mitochondria and the Golgi apparatus, and in addition, some cells of plants and algae contain chloroplasts. Unlike unicellular archaea and bacteria, eukaryotes may also be multicellular and include organisms consisting of many cell types forming different kinds of tissue.
