Which are the different types of primary cells?

Primary cell culture: This is the maintenance of growth of cells dissociated from the parental tissue (such as kidney or liver) using mechanical or enzymatic methods, in culture medium using suitable glass or plastic containers. The primary cell culture could be of two types depending upon the kind of cells in culture. Adherent cells - Cells shown to require attachment for growth are said to be anchorage dependent cells. The adherent cells are usually derived from tissues of organs such as kidney where they are immobile and embedded in connective tissue. Suspension cells - Cells which do not require attachment for growth or do not attach to the surface of the culture vessels are anchorage independent cells/suspension cells. All suspension cultures are derived from cells of the blood system because these cells are also suspended in plasma in vitro e.g. lymphocytes read less

A primary cell is a battery that is designed to be used once and discarded, and not recharged with electricity and reused like a secondary cell (rechargeable battery). In general, the electrochemical reaction occurring in the cell is not reversible, rendering the cell unrechargeable. As a primary cell is used, chemical reactions in the battery use up the chemicals that generate the power; when they are gone, the battery stops producing electricity and is useless. In contrast, in a secondary cell, the reaction can be reversed by running a current into the cell with a battery charger to recharge it, regenerating the chemical reactants. Primary cells are made in a range of standard sizes to power small household appliances.
