The structure that surrounds the cell membrane in plants is the cell wall.
The cell wall is a rigid layer made primarily of cellulose, which is a complex carbohydrate. This wall provides support and protection to the plant cell, giving it shape and allowing it to withstand various environmental stresses. Unlike animal cells, which only have a cell membrane, plant cells have this additional outer layer. The cell wall is crucial for maintaining turgor pressure, which is the pressure of the cell contents against the cell wall, helping the plant to stay upright and maintain its structure.
