Step-by-step explanation:
Leaves have various characteristics that help plants survive in different environments. They can be simple or compound. Simple leaves have an undivided blade, like a banana leaf, while compound leaves are divided into leaflets, like the leaves of a locust tree. Within compound leaves, there are two types: palmately compound leaves have leaflets radiating from a single point like the poison ivy leaf, and pinnately compound leaves have leaflets arranged along the midrib, like rose leaves.
