1. Evolution of Plants; p. 2; moderate; ans: T Proteinoid microspheres provide evidence that organic molecules in water can aggregate into cell-like structures 2. Evolution of Plants; p. 3; moderat... e; ans: F The first cell-like structures were able to use inorganic (organic) compounds as a source of energy. 3. Evolution of Plants; p. 3; easy; ans: F Most likely, autotrophs (heterotrophs) evolved before heterotrophs (autotrophs). 4. Evolution of Plants; p. 4; easy; ans: T According to the fossil record, the appearance of photosynthetic organisms was associated with an increase in free oxygen in the atmosphere. 5. Evolution of Plants; pp. 4–5; moderate; ans: T The increase in atmospheric oxygen enabled organisms to obtain more energy from organic molecules by breaking them down via respiration. 6.
