Fascinating, thanks for posting. Of course plants can see up to a point, they lean towards the sun, so must be able to see slightly to be able to do that. But this is in another league. I can't see how the necessary focal length of a lens and retina can exist or be contrived in the thickness of a leaf, with presumably no trace of it apparent by dissection. but it might be possible for the plant to resolve its view of the surroundings around it over a period of time with no lens, using the movement of shadows from everything across its surface, every day, it could simply replicate the shadows passing across it in its structure maybe. Does it also accurately replicate colours?
