Message: [QUOTE="j.w, post: 110181, member: 2221"] Anybody got a microscope? [font="Arial"]When you look at fresh water with a microscope you will likely see a variety of tiny living things. Sources of fresh water samples can include ponds, lakes, rivers, aquarium tanks or even an old rain puddle.[/font] [font="Arial"]You might see bacteria which belongs to the Kingdom Monera. [/font] Kingdom Monera (Archaebacteria & Eubacteria) Until recently, all bacteria were grouped together in one kingdom (five kingdom system). This was because their cell structure was similar. The five-kingdom system is divided into animal, plant, fungi, protist, and monera. The monera kingdom is made up of two groups called phyla. Both of these phyla are made up of one-celled organisms, which are all bacteria. None of them have a true nucleus. One-celled (unicellular) organisms whose DNA is not contained inside a nucleus are called prokaryotes (PRO care ee oats). They are bacteria. Bacteria mostly absorb their food. Some have chlorophyll. These bacteria can be round, rod-shaped, or spiral shaped. The other phylum is the cyanobacteria. They are often called blue-green bacteria. They can make their own food using chlorophyll and are mostly blue-green in color.
