Plant Adaptations and Functions

This video tutorial explores various leaf modifications in plants, focusing on their structural changes due to functional needs. It covers leaf tendrils, spines, and phodes, explaining their roles in climbing, defense, and reducing evaporation. The video also discusses insectivorous plants like the pitcher plant, bladderwort, and Venus flytrap, detailing how they trap and digest insects to meet their protein requirements.
