Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which structures surround the cells?
A
Cell Membrane and Cytoplasm
B
Cytoplasm and Cytoskeleton
C
Cell Membrane and Cell Wall
D
Cell Wall and Nucleus
Explanation: 

Detailed explanation-1: -The cell wall surrounds the plasma membrane and provides the cell tensile strength and protection. Besides the presence of chloroplasts, another major difference between plant and animal cells is the presence of a cell wall.

Detailed explanation-2: -The cell wall is the structure that surrounds the cell membrane and gives support to the cell. The cell wall provides tensile strength as well as protection to the cell.

Detailed explanation-3: -The outer lining of a eukaryotic cell is called the plasma membrane. This membrane serves to separate and protect a cell from its surrounding environment and is made mostly from a double layer of proteins and lipids, fat-like molecules.

Detailed explanation-4: -The membrane that surrounds the cell and separates it from the outside environment is the cell membrane whereas a cell wall is another structural layer surrounding the cell, next to the cell membrane.

Detailed explanation-5: -The cell wall is the outermost part of the plant cell and the cell membrane is the outermost covering the animal cells. The cell wall is made up of pectin, chitin, lignin, glycoproteins, glycolipids, sugar, and cellulose and the cell membrane is a lipid bilayer and is composed of lipoproteins and carbohydrates.
