What Do the Roots Emerging from Germinating Seeds Exhibit

Question

What do the roots emerging from germinating seeds exhibit?
A) positive gravitropism
B) negative gravitropism
C) positive phototropism
D) negative phototropism

Accepted Answer

The roots emerging from germinating seeds exhibit positive gravitropism, which means they grow downwards towards the force of gravity. This helps the roots to anchor the plant and absorb water and nutrients from the soil. The shoots, on the other hand, exhibit negative gravitropism, which means they grow upwards against the force of gravity towards light.
