I loved the second part of the course as much as the first one. This is one of the best MOOCs out there. Professor Chamowitz is funny, intriguing and engaging, and it's easy to learn while having fun. You'll learn a lot, but with lots of interesting video material, animations, additional resources and interesting facts. Unlike the first course that's mostly oriented towards plant behavior, this one goes deep into their biology, photosynthesis, cells etc., and I'd never thought I'd be enjoying learning about chloroplasts. After more than 20 years of schooling and after my PhD lectures, I think I finally know how REALLY photosynthesis works. :) All in all, if you're a layman in biology or an expert - this is the course for you. Really a gem.
