The cell wall has many important functions in a cell including protection, structure, and support cell wall composition varies depending on the organism in plants, the cell wall is composed mainly of strong fibers of the carbohydrate polymer cellulose. The plasma membrane is the outer membrane of a cell, it encloses the cell itself, maintaining specific conditions for cellular function within the cell since it is selectively permeable, the plasma membrane plays an important role in the entrance and exit of substances. Cell staining is a technique used for the main purpose of increasing contrast through changing the color of some of the parts of the structure being observed thus allowing for a clearer view there are a variety of microscopic stains that can be used in microscopy.

It is a far more complex structure, however, and serves a variety of functions, from protecting the cell to regulating the life cycle of the plant organism chloroplasts - the most important characteristic of plants is their ability to photosynthesize, in effect, to make their own food by converting light energy into chemical energy. For example, some cells are used to carry oxygen through the blood, while other cells of similar function group together to transmit nerve impulses the work of the cell is carried out by the many different types of molecules it assembles, such as proteins, lipids, carbohydrates, and nucleic acids. 1-12 of 448 results for books: cell structure and function cell structure and function cancel book format: paperback | kindle edition cell structure and.
