Life cycle of angiosperm ( diagrammatic ) |
| Answer» In flowering plants, the\xa0gametophyte\xa0generation takes place in a flower, which forms on the mature sporophyte plant. Each male\xa0gametophyte\xa0is just a few cells inside a grain of pollen. Each female\xa0gametophyte\xa0produces an egg inside an ovule.\xa0The adult, or sporophyte, phase is the main phase of an\xa0angiosperm\'s life cycle. ... Double fertilization is a process unique to\xa0angiosperms. The ovule, sheltered within the ovary of the carpel, contains the megasporangium protected by two layers of integuments and the ovary wall. | |
