Western Sydney University2019300802 Biodiversity3.4 Observing eukaryotic Protista Protista are a collection of eukaryotic organisms that do not belong in the kingdoms Plantae, Animalia orFungi. They are a diverse group of organisms which display different methods of movement, may or may notbe photosynthetic and are found in a wide range of ecosystems. Here we will look at an example of a protist,Paramecium.Parameciummoves by means of cilia which cover the whole body and beat in a co-ordinated sequence topropel the organism. The body of a Parameciumhas a definite shape which enables more efficient movement.There is also an oral groove, that due to the pattern of currents produced by the beating cilia, tends toaccumulate possible food items for efficient ingestion by the gullet. Cytoplasmic streaming helps circulatevacuoles around the cytoplasm and wastes tend to be eliminated from food vacuoles at a specific site, acytoproct, on the membrane.Parameciumhas two distinct types of nuclei – a macronucleus and a micronucleus (other ciliates also have asingle macronucleus but may have as many as 80 micronuclei depending on the species). The micronucleus isresponsible for genetic exchange and nuclear reorganisation and also gives rise to the macronucleus. Themacronucleus (also called vegetative nucleus) is essential for metabolism, mitotic division and for control ofcellular differentiation.3.4.1PROCEDURE: Making a wet mount of Parameciumculture. Watch the videos:“How to make a wet mount of Parameciumculture”“Live Parameciumunder the microscope”1)Using a plastic Pasteur pipette, place a drop of the Parameciumculture on a clean cavity microscopeslide.
