11.+Cell+Specialisation

__Cell Specialisation__
Once an organism begins to grow and develop, the cells do not stay the same. They become specialised. This means they perform different functions to one another. An example is in a leaf of a plant there are many specialised cells. The epidermal cells are see through and let sunlight through. The mesophyll cells contain many chloroplasts so lots of photosynthesis can happen in them. The guard cells control gases and water vapour that leave and enter the leaf. Each type of cell has a different role; however, they all function together.
