Abstract
The structural features of some types of cells megasporange family Rosaceae have been analyzed. Female multicellular archesporium. Sporogenous complex multy- (Potentilla alba, Potentilla reptans, Potentilla argentea) and one-layered (Fragaria vesca). Variability in the number of tetrad megaspor and megasporocytes agamo in sexual and species was found out.
