form 1 discussion about cell

Did You Know? - The cells that make up our body are so small that you would fit over 200 of them on the full stop at the end of this sentence. The word cell is derived from the Latin word cellula which means a little room. It was the British botanist Robert Hooke who, in 1664, w..

The cells discussed above use a liquid electrolyte, one cathode and an anode. Some of the major disadvantages of these cells are leakage on long term storage, corrosion due to the use of liquid acidic/alkaline solution, short life, low weightage per kg mass o..

Introduction - One of the main ideas in the modified cell principle is that new cells arise from pre-existing cells (Omnis cellula e cellula). Every new cell formed must inherit not only the nucleus which contains the genetic information, ..

An electrolytic cell consists of a container made either of glass, or any suitable plastic material called electrolytic tank, which is a bad conductor of electricity. Two electrodes (rods or plates) are placed in the tank and it is filled with the solution of the electrolyte or with molt..

Cells of the Immune System - Lymphocytes are the main cells of the immune system. They arise from stem cells present in the liver in the foetus and in the bone marrow in the adult. Comparison of cell-mediated and humoral immunity Some of them continue their m..

All living organisms, whether plants or animals, are made up of microscopic units called cells. The cell occupies the same central position in biology as the atom in the physical sciences. All living beings, plants and animals, start their life with a single cell. Some..

Properties of Cancer Cells - 1) Cancer cells show uncontrolled mitotic divisions causing unorganised growth 2) Due to uncontrolled growth and division of cells, a tumour (also called Neoplasm is generally formed) 3) Cancer cells are far le..

>In case of gas electrodes such as hydrogen the inert metal platinum, which serves as the electrical contact, is also written while representing the half-cell. A comma to indicate that they form one phase separates the two. Sometimes negative sign is put on the anode a..
