In many cases pollen from the seed plant will do the job too and such a species we call self-pollinated. This is indeed the case for sunflowers. shesaidsunflower.com/how-do-sunflowers-pollinate | |
| Aug 19, 2022 at 15:07 | comment | added | StoneThrow | The wikipedia article on plant reproduction implies that pollination means the transfer of pollen from one flower to another flower...but it also doesn't say so explicitly either. Reaching back into long-forgotten high school biology, I think that the reproductive parts of plants are stamens and pistils...and I think my question is: does one sunflower head have both, and does transferring pollen between stamen and pistil on the same sunflower head "work" as pollination? I'm nearly 100% certain there are no other sunflowers nearby. | |
| Aug 19, 2022 at 15:02 | comment | added | StoneThrow | If you have knowledge here, I wonder if you might expand your answer on this aspect: I am not very clear: why/how can a flower be "self-pollinated"? What I mean is: I take your answer to mean that a bee might pick up pollen from one area of the sunflower head and deposit it at another area on the same sunflower head, and that "counts" as pollination -- is that true? I was unclear on this specifically: whether pollination is necessarily picking up pollen from one flower and depositing it on a distinct other flower (of the same species, of course). | |
