Shoots That Grow Vertically Toward the Sun Can Be Characterized

Question

Shoots that grow vertically toward the sun can be characterized as
A) negatively phototropic and positively gravitropic.
B) negatively phototropic and negatively gravitropic.
C) positively phototropic and positively gravitropic.
D) positively phototropic and negatively gravitropic.

Accepted Answer

Shoots that grow vertically towards the sun exhibit positive phototropism, as they are growing towards the source of light. They also exhibit negative gravitropism, as they are growing against the force of gravity. Therefore, D is the correct choice.
