Biology4Kids : Cell Structure
Cells are unique to each type of organism. If you look at very simple organisms, you will discover cells that have no defined nucleus (prokaryotes) and other cells that have hundreds of nuclei (multinucleated).Humans have hundreds of different cell types.Biology4Kids : Cell Structure: Cell Membrane
Cell Membranes According to cell theory, cells are the main unit of organization in biology.Whether you are a single cell or a blue whale with trillions of cells, you are still made of cells. All cells are contained by a cell membrane that keeps the pieces inside. When you think about a membrane, imagine it is like a big plastic bag with some tiny holes.Human Cell Diagram, Parts, Pictures, Structure and Functions
