What type of plant is a black eyed susan?
Thanks for the question! This pretty climber is indigenous to my country so it’s one of my favourites. Thunbergia alata: It certainly is vascular, since it it a flowering plant: only really primitive plants are non vascular. It does have seeds: that is its primary way of reproduction. The seeds germinate so readily that the plant may become invasive in certain areas. Angiosperm of course: if you don’t know why you need to read up on plant diversity. Gymnosperms don’t form true flowers, and their seeds have no coating. Black eyed Susan obviously has a flower. And just by looking at the flower you can tell it’s a dicot (or more correctly a Eudicot). It is primarily pollinated by bees (thus Entomophily). I don’t think much research has been done on the fertilization of Thunbergias specifically, but I’d expect it to be typical of all Angiosperms. That means that they’ll be fertilized doubly (double fertilization). Double fertilization is a complex fertilization mechanism that has evolved i
