Assertion : Ginger has a prostrate-growing rhizome. Reason : Shoot growth is not effected by gravity.

Step-by-step solution

It bears some scaly leaves at the nodes, possesses a bud in the axil of the scaly leaf and ends in a terminal bud. The response of plant to wards gravity is called geotropism. The roots are positively geotropic and grow downwards, while the shoot is negatively geotropic and grows away from the gravitational pull from the ce
