How do these plants avoid self-pollination?
In my botany class we watched a movie about pollination. I was wondering how two specific plants avoid self-pollinating themselves.
So, how does the geranium and aloe plant avoid self pollination?

Answer by Dean M.
Most plants with perfect flowers avoid this by having the “male” and “female” parts of their flowers maturing at different times so self-pollination is physically impossible. Some species, like the rosebay willow-herb described near the bottom of this website http://www-saps.plantsci.cam.ac.uk/articles/broad_pollen.htm also change the structure of the flowers so self-pollination is even less likely.

And there actually several instances where geraniums (both Geranium and Pelargonium genera) have exhibited self-pollination. Just google “geranium self pollination” and the first few entries are from scientific studies.
