If the plant cell wall becomes as flexible as the cell membrane, the cell would lose its rigidity and fixed shape. It would not be able to withstand external pressure or maintain structure. The plant would become weak and unable to stand upright. The protective and supportive functions of the cell wall would be lost, affecting the plant’s survival.

Using potato pieces of equal size and measuring their initial weight ensures that any observed change is due to the solution and not differences in size or mass. This makes the experiment reliable and accurate. It helps compare results properly and clearly shows the effect of osmosis on the potato pRead more

Eukaryotic cells contain many organelles to perform different life processes efficiently. Each organelle has a specific role, such as mitochondria producing energy, ribosomes making proteins and lysosomes removing waste. This division of labour allows multiple processes to occur simultaneously, making the cell more efficient organised and capable of supporting complex life functions.

The cell interior is a coordinated system where different organelles work together inside the cytoplasm. The nucleus controls activities, mitochondria produce energy and other organelles perform specialised tasks. This coordination allows the cell to function like a small factory, carrying out life processes efficiently and maintaining balance within the cell and the organism.
