Describe an investigation into the effect of gravity on the growth response of root |
|
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. |
