Mandi did a science investigation using cut white carnations. She put the stem of one flower into water with red food coloring. She put the second flower into water with blue food coloring. Then she left the flowers overnight. The next day, she could see the colors from the water in the flower petals. Her results are shown below.

Answer 1

The conclusion that best fits the results of Mandi's experiment is:

A. The stem of the plant carries water to the flowers.

This is supported by the observation that the cut white carnations changed color based on the colored water they were placed in, demonstrating that the colored water traveled up the stem into the flower petals.
