The cell wall is a rigid outer layer in plant cells. It provides support, protection and shape, helping plants remain upright and withstand environmental stress like wind and pressure.
The cell interior contains cytoplasm, nucleus and organelles that work together. Each part performs specific functions, coordinating activities like energy production, transport and control, ensuring proper functioning of the cell.
Eukaryotic cells need organelles to perform different functions efficiently. Each organelle carries out a specific task like energy production, protein synthesis and waste removal, ensuring smooth and organised functioning of the cell.
If a plant cell wall becomes flexible, the cell will lose its rigidity and shape. It may shrink under stress and fail to support the plant, affecting its structure and stability.
