Summary - In the modern system of classification, living organisms are grouped under five kingdoms, as proposed by Whittaker (1966). The Kingdom Monera includes bacteria and blue green algae, both of which possess prokaryotic cells. Bacteria are unicellular prokaryotes that have..

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..

He found that an electric current flowed across two dissimilar metals between which was a moist substance. In his case, the moi..

The cell wall is present only in plant cells. It is made up of a complex polysaccharide (carbohydrate) called cellulose. Its function is to give strength and rigidity to the cell. It is non-living...

The word organelles (Latin: organas=instrument) is used to describe the living structures inside the cytoplasm, having definite shape, structure and functions. The various cell organelles in a cell can be broadly classified into the following two categories i. Membrano..

Each cell whether in a unicellular form like Gleocapsa or multicellular form like Nostoc, has a definite cell wall. Most often it is surrounded by a thin or thick mucilagenous sheath. The inner layer of cell wall has a chemical composition similar to bacterial cel..
