Leaves are vital organs of plants, playing a crucial role in their survival and growth. They are typically flat, thin structures attached to stems or branches. Leaves are responsible for photosynthesis, the process through which plants convert sunlight, water, and carbon dioxide into energy-rich sugars. Their diverse shapes, sizes, and arrangements aid in species identification.
Leaves also help regulate water loss through small openings called stomata and provide protection from predators and environmental stressors. Remarkably, leaves exhibit a wide range of adaptations, such as needle-like leaves of conifers and spines on desert plants. Understanding leaf characteristics is fundamental in plant identification and the study of plant ecology.
