Entomogamous flowers have evolved into two major groups: Rosids and Asterids. In each of them, they have first evolved towards a melittophilia (pollinated almost exclusively by apoids: Fabaceae, in the first group and Lamiaceae in the second) and then to a non-specialized entomogamy (pollinated by both short-tongued apoids and mainly syrphids and beetles (Rosaceae in the first group and Asteraceae and Apiaceae, in the second).From the point of view of anthophilous insects, the most important botanical families are: 1) for long-tongued insects: Lamiaceae, Fabaceae, Asteraceae carduideae,...

Plants, unlike insects, cannot move. Therefore, in sexual reproduction they cannot choose their partner. But, like any living being, they need to reproduce, mainly through cross-fertilization, to maintain the genetic diversity of their populations, a guarantee of success in adapting to the changing conditions of the environment. That is, flowering plants (Angiosperms) use pollination - through pollinators - to carry out sexual reproduction and make genetic recombination possible during the meiotic phase of cell division, when chromosomes are duplicated in metaphase and recombine in the...

Les plantes, contrairement aux insectes, ne peuvent pas se déplacer. Par conséquent, lors de la reproduction sexuelle, ils ne peuvent pas choisir leur partenaire. Mais, comme tout être vivant, ils ont besoin de se reproduire, principalement par fécondation croisée, pour maintenir la diversité génétique de leurs populations, gage de réussite dans l'adaptation aux conditions changeantes de l'environnement. En d'autres termes, les plantes à fleurs (Angiospermes) utilisent la pollinisation - par l'intermédiaire des pollinisateurs - pour réaliser la reproduction sexuée et rendre...
