Evaluate and explain this statement: An angiosperm plant could be described as the ultimate "solar energy organism."
What will be an ideal response?
The angiosperm plant could be described this way because of photosynthesis and the energy-storing (and energy-releasing) molecules it produces. However, there are other more indirect ways that plants maximize use of the sun. Molecules made through photosynthesis provide energy for the active transport that moves sugars into phloem, indirectly providing the osmotic pressure to move food around the plant. Transpiration occurs because of the warmth (and air movement) powered by the sun, which in turn provides the force to move water up and through the xylem of the plant. So, while humans, for example, expend a great deal of energy to keep a heart pumping materials around the body, a plant spends almost no energy to accomplish the same result.
