I decided to try and look at the full resolution image (found here) and think I noticed something. Generally I don’t look at the full resolution pictures, but I decided to try it here because I noted that you could see a radicle (preroot) but the image isn’t clear. So I blew it up and you can slightly make it out in the center of the image shown above.
The thing that I noticed isn’t that though. What I noticed is that if you look at the seeds to the right, it looks as if there are some hairs already growing out of the seed. Now I’m not declaring this to be the case because it is really tough to tell, but my brain is giving me the impression that there are root hairs, and I thought I’d open it up for discussion. What do you think? If it isn’t clear from the above image (which will get bigger if you click it) then click the original image link (linked above) and let me know what you think.
