Hi all, many many protists have strategies for controlling their solar light environment..with out terming it thoughtful behavior strategies...we 'neutrally?' term such behaviors as : tropisms. Some flagellate protozoa ( eg: Haematococcus pluvialis ) actually move their internal pigments to shield i...
