In which cells is surfactant produced? Planarians reproduce by two distinct strategies: asexual and sexual reproduction (Hyman, 1951). Unlike parenchyma tissue, sclerenchyma tissue can provide elastic strength to plant body and synthesize lignin which hardens the plant body and prevents decay. Its cells are isodiametric. They are live thin-walled cells with permeable walls that are undifferentiated. Some parenchyma cells have thick lignified secondary walls.
