Ascular plants grow to incredible heights. Which of the following features could be credited for their height? a. well developed vascular system b. brightly colored flowers c. numerous leaves to outcompete other plants for sunlight

The answer is A. The vascular system, filled with vascular tissue, are the crucial conduits through which water and nutrients flow through plants. Without them plants are limited to being a few inches (centimeters) tall. Leaves that get sunlight have nothing to do with a plants height.
