How is castor pollinated?

How is castor pollinated?

It reproduces with a mixed pollination system which favors selfing by geitonogamy but at the same time can be an out-crosser by anemophily (wind pollination) or entomophily (insect pollination). Its seed is the castor bean, which, despite its name, is not a bean (that is, the seed of many Fabaceae).

How does castor bean reproduce?

Since the castor bean is an angiosperm it relies on seeds to reproduce, unlike non-flowering plants that instead use spores to reproduce. The flower of the plant is simply a bunch of modified leaves. The outermost layer of these leaves being called the perianth is comprised of sepals.

Growing the plant as an ornamental or a crop is not illegal, but extracting and concentrating ricin from it is, as you would in effect be making a potent biological weapon (obviously, I do not recommend that, either).

Is castor self pollinated?

Which pollination occurs in castor?

Can castor seed prevent pregnancy?
