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 of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the 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 separates the extracellular space, outside of the cell, from the cytosol inside the cell. The plasma membrane is the border between the interior and exterior of a cell.

Detailed explanation-5: -The cell membrane surrounds the cell and controls the substances that go into and out of the cell. The nucleus is a structure inside the cell that contains the nucleolus and most of the cell’s DNA.
