[PLANT PHYSIOLOGY] Which of the following statements about age gradients within the plant body is FALSE? Select one: O a. All of the statements are true. Ob. Age gradients within the plant body reflect the plant cells' lack of mobility due to their shared walls. Ос. Age gradients within the plant body include an apical-basal gradient where the youngest cells are near the apices (tips of shoots and roots). d. Age gradients within the plant cells include walls that are youngest immediately adjacent to the plasma membrane and progressively older toward the middle lamella.

3) When she was a young child, Mélanie had a favourite swing hanging from the lower branch of a 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. Ten
