Hi
Draw a neat labelled diagram of paramecium.
Structure of paramecium
-Pellicle: It is outermost covering. It is thin and elastic. It is made up of a kind of gelatinous substance. -Cilia: The outer layer is covered with fine hair like structure called cilia.The cilia help in locomotion and capture food. -Trichocyst: The trichocysts are spindle shaped structure, which arrange at right angle towards inner side of pellicle. -Oral groove: The oral groove is oblique aperture which runs backward and situated at 2/3rd part of the body. -Cytopyge: There is small opening called cytoproct or cytopyge is present behind oral groove. It acts as anus of the paramecium. -Cytoplasm: Cytoplasm is differentiated into two parts. The outer part is thin and called ectoplasm, inner part is granular called endoplasm. -Nucleus: In the endoplasm, there are two nuclei. One is larger kidney shaped called macronucleus or mega nucleus which helps in vegetative reproduction. There is another is smaller round or spherical nucleus in the cavity of large nucleus called micronucleus, which helps in sexual reproduction. -Contractile Vacuole: There are two contractile vacuoles one at each end.It helps in absorption of water from the body and pour into the vacuole.
