- Wait so are flowers gametophytes or sporophytes? I know he says they are sporophytes at 8:43, but flowers have anthers, stamens, egg cells, sperm cells, and all the reproductive organs, so doesn't that make them gametophytes?

So refreshing to see humor and quick explanations for what may seem like complicated topics! Wonderful videos. My son and I truly enjoy them (13 yrs old). As a future Science teacher it is something I will share and link to my pages, thank you!
