Cells The basic unit of structure and function in living organisms is the cell. Because cells are very minute, they can only be seen under high magnification with the microscope. While some organisms are very simple, containing a single cell (unicellular), there are some organisms that are more complex (multi-cellular). In eukaryotes, cells often combine…

Cell Structures and Organelles
Cell Structures and Organelles Cell Surface Membrane (plasma membrane) All cells possess a cell membrane (both prokaryotic and eukaryotic). This is the outermost structure of the cell which separates the cell from its environment. The cell membrane is a thin partially permeable bilayer structure (2 layers) which has protein embedded within the layers. The layers…
Difference between Plant and Animal Cells
Difference between Plant and Animal Cells Plant and animal cells are both eukaryotic cells. However, there are distinct differences between the cells found in plants and those found in animals. The differences between the two types of cells can be seen with a light microscope. Below is a list of the major differences: ANIMAL CELLS…
Specialization of Cells
Specialization of Cells In living organisms there are millions of cells present. If all the cells in a body were the same and performed the same functions, there would be some functions that an organism would be unable to perform. As a result, some of these cells are specialized and grouped together to form tissues…
