Plant cells differ from animal cells in having an additional layer around the cell membrane termed as __________.

Cell wall

The correct answer is Option (3) -Cell wall

The additional layer around the cell membrane found in plant cells, which distinguishes them from animal cells, is called the cell wall.

The cell wall is a rigid and protective layer that surrounds the cell membrane in plant cells. It provides structural support, protection against mechanical stress, and helps maintain the shape of the cell. Unlike animal cells, which lack a cell wall, plant cells have this additional layer, composed primarily of cellulose, hemicellulose, and pectin. The cell wall allows plants to withstand osmotic pressure changes and provides a barrier against pathogens. Additionally, it contributes to the overall rigidity of plant tissues, enabling them to grow upright and maintain their structural integrity. While both plant and animal cells have a cell membrane (also known as the plasma membrane), the presence of the cell wall is a key feature that distinguishes plant cells from animal cells.
