The Power of Movement in Plants'The Power of Movement in Plants' by Charles Darwin is a groundbreaking study of how plants respond to external stimuli, particularly in regards to phototropism and other types of movement. Assisted by his son Francis, Darwin uses individual plant observations to examine the general principles governing their growth and life. This book stands as the culmination of a long line of Darwin's work in studying plants. Through his research, Darwin presents evolutionary perspectives that account for changes in plant behavioral responses and how gradual modification can enable plants to adapt extensively to their environments. |
