OCCURRENCE OF TRANSFER CELLS IN THE SPOROPHYTE OF PTERIDIUM AQUIUNUM L. KHALIDA KHATOON Abstract: Cells with wall ingrowths called transfer cells were observed in foot cells of sporophyte of Pteri- dium aquilinum L. Gametophytic cells contiguous with foot cells of sporophyte also possessed wall in¬growths. Cell walls of foot cells of sporophyte immediately adjacent to the gametophyte, had wall ingrowths on both sides. Wall ingrowths or projections, irrespective of their distribution were always delimited by plasmalemma. The distribution of cell organelles in transfer cells and their possible role in transport of nutrients is discussed. Department of Botany, University of Karachi, Karachi-32, Pakistan. |
