Answers
Explanation:
The main difference between androecium and gynoecium is that the androecium (or stamen) refers to the male part of the flower whereas the gynoecium (or pistil or carpel) refers to the female part. ... Moreover, androecium produces pollen grains while gynoecium produces ovules.
Plants may have flowers that are complete or incomplete. If a flower has sepals, petals, pis- tils, and stamens, it is a complete flower. If a flower is missing one of those, it is an incom- plete flower. Imperfect flowers are always incomplete, but incomplete flowers may or may not be imperfect.

2.A flower that has all 4 whorls of floral parts is said to be a complete flower Eg:hibiscus,rose,sunflower etc. A flower without one or more of the normal parts as capepls,sepals,petals,pistils or stamens are called incomplete flowers Eg: Rue anemone,american elm,oak,black walnut etc.
3.Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.
4.Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happened in flowers where the stamen and carpel mature at the same time, and are positioned so that the pollen can land on the flower's stigma.
