periplast मीनिंग इन हिंदी

Previously, Choanoflagellida was divided into these three families based on the composition and structure of their periplast : Codonosigidae, Salpingoecidae and Acanthoecidae.
Large ejectisomes, visible under the light microscope, are associated with the pocket; smaller ones occur underneath the periplast, the cryptophyte-specific cell surrounding.
Members of the family Codonosigidae appear to lack a periplast when examined by light microscopy, but may have a fine outer coat visible only by electron microscopy.
