|Diagram of a human cell|
I have learned, again, that cells are something that we need. This I already knew. I remembered learning about the nucleus and nuclei and how they are always protected, and the biggest. And I remembered how the cells determine exactly how we are made up. But I never remembered learning anything about a Eukaryotic cell in my life.
The cell wall: The think protective cell walls provide support and this wall also help maintain the shape of the cell. The cell wall will help prevent the cell wall from bursting and taking in too much fresh water. The cells of fungi, even plants, and algae have these thick walls.
The Plasma Membrane: All cells prokaryatic and eukaryatic, they have what is referred to as a plasma membrane. The membrane is made of proteins and phosopholipids. These regulate the movement of the materials between the outside and the inside of the cells, and function as their barrier.
