What is the primary factor driving the evolution of plant morphology?

Correct Answer: Competition for light

Step 1: Understand what plant morphology means. It refers to the shape and structure of plants.
Step 2: Recognize that plants need light to grow and survive.
Step 3: Realize that in nature, many plants compete for the same light source, especially in dense areas like forests.
Step 4: Know that this competition influences how plants grow. For example, some may grow taller to reach more light, while others may spread out their leaves.
Step 5: Conclude that the need to compete for light is a major reason why plants have different shapes and structures.
