The ovule, sheltered within the ovary of the carpel, contains the megasporangium protected by two layers of integuments and the ovary wall. Within each megasporangium, a megasporocyte undergoes meiosis, generating four megaspores: three small and one large.

WebApr 2, 2024 · For example, in conifers, the dominant phylum of gymnosperms, there are female cones that grow in the upper branches of the tree and male cones grown on the lower branches. Pollination is done mostly by the wind, carrying the male pollen grains to fertilize the megaspores on the female cones. WebThe megasporangium is surrounded by layers of sporophyte tissue called the integument. The integument and structures within (megasporangium, megaspore) are the ovule. Microspores germinate within the sporophyte tissue and become pollen grains. The microgametophyte is contained within the tough, protective coat of the pollen grain.
