ORAL GROOVE-The ventral surface of the body bears a prominent,shallow depresion called as oral grrove.It extends from the middle of the body and extends to the left side of the anterior end.
PELLICLE-The external envelops of the body is a living ,clear,firm and elastic cuticular membrane,called as pellicle.The pellicle to be series of polygonal depressions with their raised rims.The pellicle of paramecium includes a three membrane 1>outer cell membrane
2>outer alveolar membrane
3>inner alveolar membrane.
There is pit in the centre of the each alveole or alveolus which forms a polygon It is a pit in the center of each alveole or alveolus which form polygon. All the alveoli collectively form a continuous alveolar which is delimited by an outer alveolar and inner alveolar membranes..
