Question

Sandra has a houseplant sitting on her kitchen windowsill, where it receives a lot of sunlight.

Answer 1

Answer:

The cells on the shaded side of the plant will shrink, causing the opposite side of the plant to grow toward the window.

Explanation:

The cells on the shaded side of the plant will shrink, causing the opposite side of the plant to grow toward the window.

Hydrogen ions are released in the cells on the shaded side of the stem. As a result, the pH of the cells decreases that in turn activates expansins (an enzyme). This enzyme causes the opposite side of the plant to grow toward the window.
