Question

3) Draw a fabelled a fabelled diagram - Pyromessiam​

Answer 1

Answer:

Paramecium is a unicellular organism with a shape resembling the sole of a shoe. It ranges from 50 to 300um in size which varies from species to species. It is mostly found in a freshwater environment. It is a single-celled eukaryote belonging to kingdom Protista and is a well-known genus of ciliate protozoa.

Paramecium, genus of microscopic, single-celled, and free-living protozoans. Most species can be cultivated easily in the laboratory, making them ideal model organisms, well suited for biological study. Paramecium vary in length from about 0.05 to 0.32 mm (0.002 to 0.013 inch). Their basic shape is an elongated oval with rounded or pointed ends, such as in P. caudatum. The term paramecium is also used to refer to individual organisms in a Paramecium species. Paramecium is the only genus in the family Parameciidae, which resides within the phylum Ciliophora.

Paramecia are completely covered with cilia (fine hairlike filaments) that beat rhythmically to propel them and to direct bacteria and other food particles into their mouths. On the ventral surface an oral groove runs diagonally posterior to the mouth and gullet. Within the gullet, food particles are transformed into food vacuoles, and digestion takes place within each food vacuole; waste material is excreted through the anus.

A thin layer of ectoplasm (clear, firm cytoplasm) lies directly beneath the pellicle (a flexible body membrane) and encloses the endoplasm (the inner, more fluid portion of the cytoplasm). The endoplasm contains granules, food vacuoles, and crystals of different sizes. Embedded in the ectoplasm are trichocysts (spindle-shaped bodies) that may be released by chemical, electrical, or mechanical means. The precise function of trichocysts is unclear; they may be extruded as a reaction to injury, or they may be used as an anchoring device, as a mechanism of defense, or as a means of capturing prey.
