The cell wall is often described as a 'protective structure' that all plants have.
On a microscopic level, a cell wall is the main difference between a plant cell and an animal cell.
The protective structures of plants
If you've ever had a look at a plant cell diagram (you can find one here), then you'll notice that the cell has several rigid structures surrounding it.
These layers (mainly made from cellulose and protein) are collectively called the cell wall.
They act to prevent things from getting inside a cell - and they also provide the entire plant with support and structure.
Whilst animals have bones that keep their body upright, plants remain standing thanks to the rigidity of many millions of cell walls.
Plants also employ a number of other physical forms of 'self-defense' to protect themselves from predators - everything from the thorns on roses through to the microscopic blades on meadow grass fall into this category.
