Did the direction the seed was facing change how the roots and stems grew? Include in your answer how the growth looked for each of the four seeds. Plants do not have any sensory organs so how do the stems of a plant know to grow up toward the light and the roots of a plant to grow down toward the water?
Describe how the roots looked in comparison to the stems; include color and any other characteristics you could see.
Plants may not be motile but they are capable of movement. Research phototropism and geotropism, how are they different and how are they the same?
