Unraveling the Control and Coordination of Plant Growth: Understanding Phototropism and Gravitropism

The video explains how plant growth is controlled and coordinated by hormones, particularly auxin. It covers how plants respond to environmental stimuli like light and gravity through processes called phototropism and gravitropism. Phototropism involves plant shoots growing towards light due to auxin distribution, while gravitropism involves shoots growing against gravity and roots growing with gravity. The video concludes with a recap of these concepts.

What is gravitropism and how does it differ in roots and shoots?

How does the distribution of auxin affect the growth direction of plant roots?

Summarize the key points about the control and coordination of plant growth discussed in the video.
