Explain the effect of gravitational rotation on the growth of roots and leaves in Caulerpa

Sagot :

Answer:

Plants' growth response to gravity is known as gravitropism; the growth response to light is phototropism. ... As a result, root cells on the upper side of the root grow longer, turning the roots downward into soil and away from the light. Roots also will change direction when they encounter a dense object, such as a rock.
