Summary Introduction
To determine:
How do statoliths and auxins participate in gravitropism.
Concept introduction:
In plants, growth of the shoots occurs in upward direction and roots grow downwards toward gravity irrespective of the orientation of the seed. Whether the seed is oriented upside down, sideways, or right side up, the pattern of shoot and root growth remains the same.
