Effect of Light Color on Plant Growth

A group of students conducted an experiment to measure the effect of different light colors on plant growth. They set up three identical pots containing the same type of plant, watering schedule, and soil type. One pot was placed under red light, another under blue light, and the third under green light. After four weeks, they measured the height of the plants.

The results were as follows:

• Red light: 12 cm
• Blue light: 15 cm
• Green light: 10 cm

Based on this data, which color of light resulted in the tallest plant growth?
