in this paper we have traced the evolution of the cytoplasmic organelles in the female germinal cell of pisum sativum l. , from the beginning of meiosis to the early stages of the maturing megaspore , in order to correlate the morphological changes with the physiological aspects of megasporogenesis.a process of intense cytoplasmic vacuolation takes place in the megaspore mother cell ( mmc ) during prophase i , probably proceeding from the smooth endoplasmic reticulum and dictyosomes ;
