In most angiosperms, the flowers are perfect: each has both microsporangia and megasporangia. ... Some angiosperms are imperfect, having either microsporangia or megasporangia but not both. ... 2 synergid cells. In several (perhaps all) angiosperms, they secrete an attractant that guides the pollen tube through the micropyle...

The vast array of angiosperm floral structures is for sexual reproduction. The angiosperm life cycle consists of a sporophyte phase and a gametophyte phase. The cells of a sporophyte body have a full complement of chromosomes (i.e., the cells are diploid, or 2n); ... Angiosperms are vascular plants, and all vascular...

Overview of sexual reproduction ... One final unique feature of sexual reproduction in flowering plants is the development of fruit. Following fertilisation, as each ovule form a seed, the ovary swells to form the fruit. The biologist's definition of a fruit is simply an organ for dispersing seeds.
