Detailed explanation-1: -Which most accurately describes the relationship between cell and plasma membranes? Only eukaryotic cells have plasma membranes that are composed of lipids. Only prokaryotic cells have plasma membranes that are composed of proteins and lipids.
Detailed explanation-2: -The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
Detailed explanation-3: -Both prokaryotic and eukaryotic cells have a plasma membrane, a double layer of lipids that separates the cell interior from the outside environment. This double layer consists largely of specialized lipids called phospholipids.
Detailed explanation-4: -The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not.
