Paramecium Caudatum is a species of unicellular organisms belonging to the genus Paramecium of the Phylum Ciliophora. They can reach 0.33mm in length and are covered with minute hair -like organelles called cilia which are used in the cells movement through the water and ingestion of food into the cytostome. The cells also has many other organelles which help it to function such as the cell membrane which acts as a form of transport allowing contractile vacuoles to ‘get rid of’ water in the cell. Another organelle in the paramecium cell is the anal pore which helps keep the cell water free by transporting any unwanted material out of the cell.
Like most eukaryotic cells paramecium caudatum has a nucleus but what makes this cell special it that I as two nucleus (large and small) the large nucleus acts as the brain of the cell controlling it as well as holding the DNA of the cell, the small nucleus otherwise known as micronucleus are produces by the large nucleus and is responsible for the genetic recognition that occurs during cross-fertilisation. Another organelle in the cell called a food vacuole is used by the cell as a form of digestion with the help of lysosomes to ‘break down’ food molecules in the vacuole.
The last organelle processed by the paramecium cell is the Pellicle which is made up of a thin, gelatinous substance produces by the cell acting as a soft armour coating the cell (used for protection)
