1.	Question : Describe the structure of a typical embryo sac found in flowering plants . Why is it generally referred to as monosporic ?
Answer» Solution :The process of development of a gametophyte or embryo sac from a megaspore is called megagametogenesis. The nucleus of megaspore undergoes three successive mitotic divisions forming high haploid NUCLEI. The megaspore enlarges into an oval SHAPED STRUCTURE called embryosac . The polar nuclei MAY fuse to FORM a secondary nucleus . It is a monosporic type of development and embryo sac is termed monosporic .
