Correct Answer: To direct plant growth towards or away from stimuli.
Step 1: Understand what tropisms are. Tropisms are how plants grow in response to different things in their environment.
Step 2: Identify the types of environmental stimuli. These can include light, gravity, water, and touch.
Step 3: Learn how plants respond to these stimuli. For example, plants may grow towards light (positive phototropism) or away from gravity (negative geotropism).
Step 4: Recognize the primary purpose of these growth responses. The main goal is to help the plant survive and thrive by optimizing its access to resources like sunlight and water.
