Question

Cyanobacteria were the first photosynthetic organisms. How were they responsible for allowing higher life forms to evolve?

Answer 1

Cyanobacteria were unicellular organisms that were supposed to have created higher life forms through symbiosis. Symbiosis is interaction between two different organisms living in close physical association, typically to the advantage of both. However, cyanobacteria began to 'eat' each other and this is how they evolved into larger, more complex cells. The parts of indigested bacteria evolved into organelles such as mitochondria, nuclei, and the ER. This is the beginning of the evolution from simple, unicellular organisms, to simple multicellular organisms, to complex multicellular high life forms. i hope this helped you! :)

Answer 2

true that, cyanobacteria evolved into higher life forms through the process of endosymbiosis as outlined by tafkas77 above.

Answer 3

AAAAA- ha! ENDOsymbiosis!!! Thank you, mphetang. I knew it was symbiosis but couldn't remember the specific term! If I would've remmebered that I wouldn't have written so much, lol. Thanks! Teamwork!

Answer 4

my pleasure!!!!!yah teamwork hey, lol..
