#Paramecium: #Nutrition,Osmoregulation & Excretion/पोषण और उत्सर्जन कैसे होता/L-3#NEET#BSc#PGT#GIC

In this video lecture class I describe about Nutrition, Osmoregulation and Excretion in Paramecium. Paramecium exhibits holozoic or animals like mode of nutrition. The process consists of following step : Food. Ingestion of food, Digestion and Assimilation, Cyclosis. During excretion, The waste products such as urea, uric acid and other nitrogenous compounds produced as a result of catabolic activities of the body, also diffuse out through the general body surface. The amount of water in body is controlled by two contractile vacuoles present one on either end of the body. Excess of water from cytoplasm is collected in the microtubules of endoplasmic Reticulum. from here water is passed on to the nephridial tubules and to feeder canal.On getting filled the ampulla discharge it in the contractile vacuoles. The contractile vacuole enlarge gradually by receiving water. When they grown to iss maximum size vacuole contracts( systole) and empties it's water to exterior through the canal that connect it with a pore in the pellicle. When the vacuoles is in state of Diastole i.e. fully distended, the feeder canal disappeared as a small streaks soon after the systole.    • #Paramecium in detail/L1/#पैरामीशियम की सं...      • #Paramecium L-2#Infraciliary System#Tricho...      • #Reproduction in Paramecium/L-4/Conjugatio...
