In botany, leaves are classified into two main types: simple leaves and compound leaves. Simple leaves refer to leaves that have a single, undivided blade. They can vary in shape, size, and margin, but they are not divided into smaller leaflets like compound leaves.
Simple leaves are usually arranged singly along the stem or in pairs opposite each other, and they can also be found in whorls or alternate patterns. They play a vital role in the process of photosynthesis, where they absorblight energy and convert it into chemical energy to provide food for the plant.
These leaves also assist in the exchange of gases, allowing the plant to take in carbon dioxide and release oxygen. Additionally, they help regulate waterevaporation, provide support for reproductive structures, and serve as a site for various physiological processes within the plant.
Study Guide
