Slime Moulds: Notes Clas­si­fi­ca­tion: Slime moulds are sapro­phyt­ic pro­tists. They feed on decay­ing organ­ic mat­ter, such as twigs and leaves.

Cell Enve­lope Def­i­n­i­tion: A chem­i­cal­ly com­plex, three-lay­ered struc­ture found in most prokary­ot­ic cells, par­tic­u­lar­ly bac­te­r­i­al cells. Lay­ers: Gly­co­ca­lyx (out­er­most). Cell

Prophase I: Longer and more com­plex than prophase of mito­sis. Sub­di­vid­ed into five phas­es based on chro­mo­so­mal behav­ior: Lep­totene, Zygotene,
