None of the above
Explanation: 

Detailed explanation-1: -Plant cells are surrounded by a tough extracellular matrix in the form of a cell wall, which is responsible for many of the unique features of a plant’s life style.

Detailed explanation-2: -Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape. Animal cells simply have a cell membrane, but no cell wall.

Detailed explanation-3: -(i) Cell wall is present in both plant and animal cells. (ii) Cell membrane is present only in plant cells.

Detailed explanation-4: -Unlike the eukaryotic cells of plants and fungi, animal cells do not have a cell wall. This feature was lost in the distant past by the single-celled organisms that gave rise to the kingdom Animalia.

Detailed explanation-5: -A cell wall is a rigid and tough layer that provides structural support and protection to the plant. The cell wall is exclusively present in plant cells and is absent in animal cells.
