How would shoot and root growth be affected by a mutation that caused plants to lose the ability to polymerize glucose into star
Anastaziya [24]

Answer:

b) Lateral branch shoots would grow more horizontally and have less of a tendency to turn upward.

d) Lateral branch roots fully embedded in soil would grow randomly upward and downward.

e) Roots breaking the soil surface would grow upward.

Explanation:

Inside the amyloplasts of the common bean the starch granules resemble variously sized cotton balls stuffed into a balloon. Under normal circumstances amyloplasts do nothing more than sit on the bottom of special gravity-sensing cells. When a plant is knocked over, the amyloplasts slide from what was recently the bottom of the cell onto a formerly vertical wall. Somehow, this movement is sensed and relayed to cells that secrete the growth-regulating plant hormone auxin.

Since the plant has lost the ability to transform glucose into the granules. The plant can´t differentiate between up or down because gravity is what causes these granules to settle down.
