Choice 2 is correct.
Explanation: Colonization of the land by plants was a major event in the evolution of plants but was independent of the direct interaction between any symbiotic relationship. On the other hand, photosynthesis was a symbiotic relationship between primitive cells and organelles capable of light-capturing and carbon fixation. Further, origin of eukaryotes also required direct physical interaction between primitive cell and mitochondria-like cells. Finally, nitrogen fixation is a phenomenon which still can be seen as a direct symbiotic relationship between nitrogen fixing bacteria and a higher plant.

mestion Completion Status: Why did I suggest that the secret to life is electrons and protons? A. Because redox reactions are necessary for all of the reactions in live cells and these redox reactions require both H+ and electrons B. Because electrons carry a negative charge and protons have a positive charge C. Because most (not all) cells need electron transport and H+ gradients to make ATP D. Because electrons are necessary for the electrical responses of the cell (like...
