Light Intensity and Sunflower Growth

Easy Research Summaries Interpreting Results

In a controlled experiment, researchers studied the effect of light intensity on the growth of sunflower plants. They placed groups of sunflowers under three different light conditions: low, medium, and high intensity. Over a period of six weeks, they measured the height of the plants weekly. At the end of the experiment, the average heights of the sunflowers were recorded as follows:

Low intensity: 15 cm
Medium intensity: 30 cm
High intensity: 45 cm

Based on these results, which statement best summarizes the relationship between light intensity and sunflower growth?

Higher light intensity correlates with increased growth in sunflower plants.

Sunflower plants grow best with low light intensity.

There is no noticeable effect of light intensity on sunflower growth.

Medium light intensity produces the tallest sunflowers compared to the other conditions.
