The following points highlight the three types of cell surface projection. The types are: 1. Cilia and Flagella 2. Pseudopodia 3. Microvilli. Type # 1. Cilia and Flagella: Cilia and flagella are similar whip-like mobile structures that extend from the plasma membranes of unicellular organisms (Paramoecium, Chlamydomonas) and many animal cells (tracheal cell, gut of worm, spermatozoon etc.) Cilia and [...]
In this article we will discuss about Cell Surface Antigens:- 1. Meaning of Cell Surface Antigens 2. Types of Surface Antigens 3. Functions. Meaning of Cell Surface Antigens: Cells are antigenic. This means that when cells of one species are injected into another species, the recipient will first identify the injected cells as being of foreign origin and start producing [...]
The following points highlight the five main changes of cell surface property of transformed cells. 1. The glycolipids and glycoproteins present on the surface of the normal cells are altered in transformed cells. The general structure of the plasma membrane is not modified. But the cell surface proteins are much more mobile in transformed cells than in normal cells. As [...]
