Detailed explanation-1: -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-2: -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-3: -Cell wall: in plant cells, gives the cell a rigid rectangular shape, helps to keep the organelles inside the cell, and does not let the cell burst due to changes in pressure.
Detailed explanation-4: -Which of the following statements is true about the cell wall? Sol: (d) The cell wall is mainly composed of cellulose.
Detailed explanation-5: -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.
