Why do plants lose their leaves and what is the significance of this process in their growth and development?

Plants lose their leaves as a natural response to changing seasons or environmental conditions. This process, known as leaf abscission, allows plants to conserve energy and resources during periods of limited sunlight or water availability. By shedding old leaves, plants can redirect nutrients to new growth, promote photosynthesis, and prepare for the next growing season. Overall, leaf loss is essential for plant growth and development, enabling them to adapt to their surroundings and thrive in varying conditions.
