Plant Responses to Stimuli

The video tutorial explores how plants respond to various stimuli such as water, gravity, light, and touch. It includes experiments demonstrating these responses, focusing on roots and shoots. Activities involve observing plant behavior in different conditions, such as roots growing towards water and shoots bending towards light. The video also highlights specific plants like Mimosa pudica and Venus flytrap, which exhibit unique responses to touch.
