[11] It gives rise to the hypocotyl, shoot apical meristem, and ...

This allows the bottom cells of the shoot to continue a curved growth and elongate its cells upward, away from the pull of gravity as the auxin move towards the bottom of the shoot. [7] As plants mature, gravitropism continues to guide growth and development along with phototropism. While amyloplasts continue to guide plants in the right ...
