What is thought to have been the order of evolution of organisms on Earth, from the earliest cells to the most complex organisms existing today?
Simple prokaryotes, unable to make their own nutrients, that gradually adapted to eukaryotes.
A lichen is a close association between millions of fungal and algal cells that are specialized to perform different functions. Would you consider a lichen to be a colonial organism? Explain why or why not?
Yes, because it has many organisms that are specialized to perform specific function for the good of the overall organism.
