I didn't plan on watching this, I've just stumbled into this but got carried away with his interesting speech.

At what point does the microspore become known as the pollen grain? Is it as soon as the microspore mother cell has divided by meosis to produce the microspores, that they are considered pollen grains OR is it when division by mitosis occurs producing the generitive & tube cells enclosed by a thick, that it is considered to be a pollen grain.

Acid wash jeans soooo hipster

that was actually surprisingly interesting

@piprod01 It is a small world, but it seems to be getting larger. I'd never have dreamt that I'd be able to aquaint myself with so many people as I do now with this medium. Here, you get to see a persons mind. You can't do that so easily with those you meet out in the streets. A pleasure.

The commercial was more interesting than the speech
