Plant Adaptations and Responses

The video discusses how plants respond to various stimuli such as light, temperature, and touch, and how they adapt to their environments. Examples include sunflowers facing sunlight, bean plants leaning towards light, and mimosa pudica closing its leaves when touched. The video also covers plant adaptations like cacti developing thorns to conserve water and aquatic plants having hollow stems to float.
