A fundamental difference between plants and animals concerns the ability to

Which of the following are involved primarily in the translocati9on of sugars from the leaf to the root?

Which of the following LEAST likely to be a factor in the movement of water through a terrestrial plant?

Carbon dioxide is passed into a solution of bromthymol blue indicator until the acid solution turns yellow. A sprig of elodea is then placed into this yellow solution. After a few hours in the sunlight, the yellow solution turns blue. The purpose of this expe3riment is to show that
