-Suppose you laid a seedling on its side so that the root was parallel to the ground. Several hours after the change in position, where in the root cells position A, B, or C in Figure 37.2 above) would you find the amyloplasts?

Question

Quizplus · Accepted Answer

Amyloplasts are specialized plastids that contain starch granules and are involved in gravity sensing in plants. In root cells, amyloplasts are typically located in the columella cells at the tip of the root (position A in Figure 37.2). When the root is reoriented, the amyloplasts will sediment to the lowest point of the new orientation, which would still be the columella cells in this case.
