Final answer:
Simple leaves and compound leaves differ in the number of leaflets, but both are involved in photosynthesis and have stomata. Modified leaves have specialized functions, such as protection or support. Examples of modified leaves include spines, tendrils, and bracts.
Step-by-step explanation:
Simple leaves and compound leaves are two types of leaves found in plants. The main difference between them is the number of leaflets. Simple leaves have a single leaf blade, while compound leaves have multiple leaflets attached to a common stalk, called a rachis. For example, a maple leaf is a simple leaf, with a single blade, while a fern leaf is a compound leaf, with multiple leaflets attached to a central stalk.
Despite their differences, simple and compound leaves also have some similarities. They both function as the main site for photosynthesis in plants, where they convert sunlight into energy through the process of photosynthesis.
Both types of leaves also have stomata, which are small openings on the surface of leaves that allow for gas exchange and the release of water vapor.
Modified leaves are specialized structures that have evolved to serve functions other than photosynthesis. Examples of modified leaves include spines, such as those seen on cacti, which protect the plant from herbivores. Tendrils, like those found on pea plants, help the plant climb and support itself. And bracts, which are modified leaves that often have bright colors, attract pollinators to flowers.
