Tropism

The video explains how plants grow in specific directions in response to external stimuli, a phenomenon known as tropism. It covers different types of tropisms: phototropism, where shoots grow towards light; geotropism, where roots grow in the direction of gravity; hydrotropism, where roots grow towards water; and thigmotropism, where vines and tendrils coil around objects upon contact. These growth responses help plants adapt to their environment and obtain necessary resources.
