The following points highlight the three main types of cytoskeletal structures of eukaryotic cell. The types are: 1. Microfilaments 2. Intermediate Filaments 3. Microtubules. Cytoskeletal Structure of Eukaryotic Cell: Type # 1. Microfilaments: They are ultramicroscopic long, narrow cylindrical rods or protein filaments which occur in eukaryotic plant and animal cells. Microfilaments are made up of actin (also present in [...]
The following points highlight the nineteen important functions of cell membranes. 1. The cell membranes cause compartmentalization. As plasma membranes they separate the cells from their external environment. As organelle coverings, they allow the cell organelles to maintain their identity, internal environment and functional individuality. 2. Plasma membrane protects the cell from injury. 3. The membranes allow the flow of [...]
The below mentioned article provides biology notes on Eukaryotic Cell. A eukaryote cell is the one which has an organised nucleus and several membrane covered cell organelles. Except monera, the cells of all other kingdoms have eukaryotic organisation. Cell wall is present in cells of plants, fungi and some protists. It is absent in animal cells and some protists. Wall [...]
