Going from the dimmest type of Red dwarfs )Say Wolf 359) to the brightest )Say Lalande 21185), what would the plant life on Earthlike exoplanets look like )Assuming it's very similar to Earth in terms of everything, but it doesn't have to be exact)? Obviously, it'll be much darker than our plants, but how dark? And could our plant life adapt to it? And what would its biology be? Or it's possible functions?
Btw, this is for my book idea, but I'm not restricting it to just that.
