Question

Kathryn planted beautiful tall shrubs in her backyard to create a shady area to sit and read her books. After a few weeks, she notices that her sunflower plant stems are leaning to the left as opposed to standing straight. She sees the leaves just barely reaching the sunlight, and the rest of the plant is engulfed in the shade. A few more weeks pass, and the plants are leaning even more to the left! This time their leaves are almost entirely in the sunshine.

How and why did the plants change in response to the difference in their environment?

Answer

Kathryn did not realize when she planted the shrubs in her yard that she would not only shade her reading spot, but she would change the environment for her sunflower plants too. The plants were covered in shade, and they need sunlight to make their food. The plant cannot get up and walk away because they have rooted in the soil, so instead, the stem and leaves lean in the direction of the sunlight. Over time the plant can lean far enough to collect the sunlight it needs.
