Which of the following is most likely to be true about the plant, based on the available data? A. It is probably an aloe vera plant. B. It probably has fibrous roots. C. It probably does not bear fruits. It will probably grow into a tall tree.

Over time, Mélanie grew older, and eventually moved out of her parent's house. Now, when Mélanie returns to visit her parents, the tree is much larger than it was when Mélanie was just a young child, but her swing is still hangingg at approximately the same height. Using concepts and terms related to plant growth seen in class, briefly explain how this phenomenon is possible. Tenarrow_forward
