PORELLA DEVELOPMENT OF SPOROGONIUM ZYGOTE Divides transversely Epibasal cell---- Hypobasal cell- ---- doesnot divide further---acts as SUSPENSOR and function as HAUSTORIUM Epibasal cell—divides---forms 3-celled embryo Redivides —irregularly Transversely & vertically and forms Multicellular & filamentous embryo Foot,setae & capsule begines to differenciate but no clear cut distinction OUTER CELLS-----Forms---- AMPHITHECIUM--- CAPSULE WALL INNER CELLS—FORMS— ENDOTHECIUM —FORMS— ARCHESPORIUM ---DIVIDES TO FORM— SPOROGENENOUS TISSUE CELLS WHICH STOPS DIVIDING Behaves as –SPORE MOTHER CELLS ----MEIOSIS-----HAPLIOD SPORES CELLS which continue to divide---become –ELATOR MOTHER CELLS-----FORM— ELATORS —WHICH ARE SHORT,TAPERING AT BOTH ENDS with 1-2 spiral thickenings Mature sporogonium is protected by calyptra —develops from ventor & is multicellular Perianth ---formed by fusion of 2-distal bracts present below the archegonial cluster 11/22/2011
