A secondary cell differs from a primary cell in that a secondary cell can be recharged and a primary cell can only be restored. 1-5 IT0335 . The factors that affect the VOLTAGE RATING of a cell are the material the electrodes are made of and the composition of the electrolyte.

Differences between primary and secondary cell wall in plants. 1. It is formed in a growing cell. It is formed in a mature cell. 2. It lies inner to the middle lamella. It lies inner to the primary cell wall outside the cell membrane. 3. It is present in all the plant cells.

The cell culture may be divided into three according to their history: 1) primary, 2) secondary and 3) continuous cell culture. The primary and secondary cells are usually diploid cells. Primary cell lines derived directly from an intact tissue like animal's embryo or kidney. Secondary cells are derived from primary cultures.

The main difference between primary and secondary cell culture is that the primary cell culture contains the cells directly obtained from host tissue, whereas the secondary cell culture contains sub-cultured cells from primary cell culture. Furthermore, cells are dissociated from the host tissue either through mechanical or enzymatical digestion. In addition to these, the cells in the primary ...

Primary Cell Culture: Primary cell cultures have finite life spans. As explained above, this is because the growth of cells exhausts substrate and nutrients and leads to accumulation of toxic metabolites. As a result, gradually the growth rate of cells drops, leading to the death of cells. Secondary Cell Culture: Secondary cell culture prolongs ...

Primary Cell Culture Applications. Primary cell culture is increasingly being used as a major tool in cellular and molecular biology, providing excellent model systems for studying the normal physiology and biochemistry of cells (e.g., metabolic studies, aging, signaling studies), the effects of drugs and toxic compounds on the cells and mutagenesis and carcinogenesis.

Classification of Cells or Batteries . Electrochemical batteries are classified into 4 broad categories. A primary cell or battery is one that cannot easily be recharged after one use, and are discarded following discharge. Most primary cells utilize electrolytes that are contained within absorbent material or a separator (i.e. no free or liquid electrolyte), and are thus termed dry cells.

SECONDARY CELL CHEMISTRY As stated before, the differences between primary and secondary cells are, the secondary cell can be recharged and the electrodes are made of different materials. The secondary cell shown in figure 2-3 uses sponge lead as the cathode and lead peroxide as the anode. This is the lead-acid type cell and will be used

Primary Immune Response . Memory B-cells are long-lived plasma cells that are formed mainly in the germinal centres.. Firstly, during the primary immune response, naïve B-cells are activated by T-cells. after that, B-cells move to secondary lymphoid organs like the spleen and lymph nodes where they enter B-cell follicles or germinal centres within the cortex.
