52.

How many food vacuoles or gastrioles are present in paramecium ?A. OneB. TwoC. FourD. Numerous

Assertion : Paramecium takes food by exocytosis. Reason : In paramecium, ejection of undigested material occurs through endocytosis.A. Both Assertion and Reason are true and Reason is the correct explanation of assertion.B. Both Assertion and Reason are true, but Reason is not the correct explanation of assertionC. Assertion is true, but Reason is falseD. Both Assertion and Reason are false

Answer» Correct Answer - D
In paramecium food particles are injected into a food vacuole formed by the endoplasm (endocytosis). The vacuole follows a distinct pathway through the endoplasm, where undigested material is egested (exocytosis).
