👉 Leaflessness is a condition where the leaves of an organism, such as a plant or tree, do not grow on them. This can occur due to various factors such as lack of sunlight, water, nutrients, or other environmental conditions. In plants, this happens when there are no chlorophyll molecules in the leaves, which is responsible for photosynthesis, the process by which plants convert light energy into chemical energy. Without chlorophyll, the plant cannot produce its own food and will die.
