Plant root systems can detect and respond to gravity within 30 minutes to a few hours.

Question

Quizplus · Accepted Answer

Plant root systems have specialized cells called statocytes, which contain statoliths (dense particles) that can sense gravity. This allows the plant to adjust its growth direction in response to gravity, a process known as gravitropism. The detection and response can occur within 30 minutes to a few hours, depending on the species and conditions.
