Question
Chapter 24, Problem 5MCQ
Summary Introduction
Introduction:
The orientation of a plant in response to the stimulus is known as the tropism. The plant may grow towards or away from the stimulus in response to the stimulus. The different types of tropism respond to different types of stimuli such as light, touch, and gravity.
