Write brief notes on the kingdoms of life.

Living organisms are divided into groups with members that have basic similarities: the broadest divisions are called kingdoms. There are five kingdoms of life: monera, protista, fungi, plantae, and animalia. Every living thing is made up of at least one cell, although some of them are so small that they can only be seen under a microscope.

Monera

The simplest of organisms are the monera, they are almost all microscopic. This kingdom includes 2 major divisions; the Eubacteria, and the Archaebacteria.  Each individual has only one prokaryotic cell—a cell that has no membrane bound nucleus or organelles; there are no structures inside the cell. The Archaebacteria are found in the most extreme places on earth, as they include methanogens which produce methane. Some monera can produce their own food by photosynthesis like plants do, but many cannot. Some have whip like flagella that allow them to move. Bacteria and blue-green bacteria (that are able to produce their own food from water, carbon dioxide and sunlight by photosynthesis) belong to the monera.

Protista

Protista are much larger than bacteria but are single-celled organisms nonetheless. The major difference between protista and monera is the organisation of the cell. The cells of protista have a separate nucleus and the cytoplasm is much more complicated than that of monerans. Protista are eukaryotes. Most protista can move. Some produce their own food by photosynthesis (like one celled algae), others must ingest other living things. Amoebae, some algae, diatoms and other organisms belong to the protista.

Fungi

Unlike protists and monerans, fungi are formed from many different cells. Fungi include both single-celled (yeasts) and multicellular (molds, ...
