The Cell Wall
The Cell Wall is the most outer layer of a plant cell. It contains three contributing layers to the wall. These three layers include the Middle Lamella, the Primary Cell Wall, and on some cell walls the Secondary Cell Wall. The Middle Lamella is a layer that contains pectins. Pectins are what help with cell adhesion. In simple terms, this means that this helps all cells stick together to stay rigid. The Primary Cell Wall is the layer that acts as protection towards a cell when being attacked by viruses, it also acts as strength and stability for the entire cell. The Secondary Cell Wall only appears in some plant cells. It develops when the primary cell wall finishes its division and growth, this causes the wall to thicken which develops the Secondary Cell Wall. Another important act the Cell Wall performs is communication to other cells. It also regulates cell growth.
Why is the Cell Wall the Most Important Organelle?
- The Cell Wall's primary wall acts as a essential line of defense from viruses that attack the cell. Without this protection from the Cell Wall, the organelles inside the cell would suffer the consequences and would be completely compromised.
- It is vital for communication with other cells. If there were no forms of communication between the trillions of cells in a tree, it would not be capable of distributing the nutrients needed for it to survive. This example is parallel with hundreds of other plants.
- The Cell Wall provides strength and stability to a cell's structure mechanically. The cell wall is what gives plant cells their regular and usually hexagonal shape. It also contributes to the overall structure of the host that the cell is in. For example, the cell wall contributes to holding up a sunflower and its rigidity.
- The Cell Wall's Middle Lamella layer contains the pectins that act as the adhesive which keeps the trillions of cells in a plant sticking together. If there was no cell wall, the cells of a plant would not stick together nearly as good as cells with cell walls.
