As far as I know green algae and thus plant chloroplasts evolved from a group of photosynthetic bacteria called prochlorophytes (are they cyanobacteria? The literature I'm reading isn't very clear on this, but I guess they are...) which have as photosynthetic pigments chlorophylls a and b and carotenoids (no phycobilins!), such as green algae and plants do. However, I am not 100% sure if the reading I made from the literature is correct, especially in whether prochlorophytes are cyanobacteria or not. So, am I right? I'd like to hear your opinion. Thanks. PS - I'm an undergraduated student taking college's 1st year on Microbiology at Lisbon's University Faculty of Medicine (Medical School).

I am taking Microbiology at college (1st year) and I don't like chemistry that much (especially physical chemistry and thermodynamics ) though I have it. I am expecting to change to medicine or dentistry (even nursery) next year, so I won’t have to take all this heavy doses of chemistry and mathematics in its purest forms. I really prefer anatomy, physiology, cell/molecular biology and stuff rather than chemistry, physics and math...
