(i) In glass house A, more fruits will be produced because pollinators enable cross-pollination between male and female flowers, increasing fertilization chances. In glass house B, without pollinators, fewer fruits will form due to limited pollen transfer.
(ii) Ovule becomes seed, ovary forms fruit and petals, sepals, stamens and stigma shrivel and fall off after fertilization.
