Facilitates the roots of plants going down towards gravity and the stems to rise up away from gravity. ... Thus, the difference is that geotropism is driven by gravity and phototropism is driven by light.

Answer:
a plant hormone which promotes leaf detachment, induces seed and bud dormancy, and inhibits germination.
Answer:
A. 3/16
Explanation:
The four possible outcomes for Stem length are:
Tt, tT, TT and tt.
The dominant trait (tall stems) will manifest itself in 3 out of 4 outcomes, so its ratio is 3/4.
The four possible outcomes for flower coloration are:
Rr, rR, RR and rr.
The non-dominant trait (white flowers) will manifest itself in 1 out of 4 outcomes, so its ratio is 1/4.
Multiplying both ratios gives us the ratio of offspring that have tall stems and white flowers:

Therefore, the answer is A. 3/16
