Detailed explanation-1: -Plant cells have a cell wall, a large central vacuole, and plastids such as chloroplasts. The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection. The central vacuole maintains turgor pressure against the cell wall.

Detailed explanation-2: -The correct option is B cell wall. In addition to the plasma membrane (cell membrane), plants have an additional protective layer called the cell wall.

Detailed explanation-3: -A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.
