what is osmoregulation how it is done in unicellular organisms
Answers
Answer:
Explanation:
Osmoregulation in unicellular organisms is by active transport. For example in Paramecium - osmoregulation is done by organelles called contractile vacuoles.These contractile vacuoles are spherical shaped structures surrounded by a series of radiating ducts.
Answer:The process of maintaining the water content and ion concentrations in the body is called osmoregulation .
Explanation:The unicellular organisms like Amoeba and Paramecium lack special excretory organs for the removal of metabolic waste products such as CO2 and ammonia. CO2 diffuses out through the cell membrane in these animals. Nitrogenous waste I.e., ammonia along with water is excreted through contractile vacuole. All these waste materials enter the contractile vacuole which makes it attain full size. The vacuole then moves close to the plasma membrane. When the contractile vacuole comes in contact with the plasma membrane,the vacuole brusts and the waste content are thrown out of the body. This completes the process of excretion. The main function of contractile vacuole is to maintain osmoregulation.
