Zea mays, an angiosperm. How is it pollinated? and Orchid inflorescence

Zea mays, an angiosperm. How is it pollinated?



Seriously. For being the most grown crop in North America, I cannot find any information on it. So, Zea mays, or corn, an angiosperm, how is it pollinated? Insects? Wind? Animals? I need it for AP Bio.


inflorescence best answer:

Answer by Michael K
It is wind pollinated. I'm sure insects could also help but for the most part it is the wind. The many male anthers are located at the very top of the plant and the female tassels which look like silk strings are each located where the cob will be. This is why corn grows best when planted in larger blocks, so that there will be plenty of pollen blowing around because each silky string on the female parts, once pollinated, will create a single kernel of corn.
