What is the main function of nodes in plants?

• A. To store energy
• B. To transport nutrients
• C. To attach leaves
• D. To facilitate reproduction

Answer: (C)

The main function of nodes in plants is to attach leaves. Nodes are specific points on a plant stem where leaves, branches, and flowers emerge. Each node serves as a critical junction for growth, allowing the plant to spread its leaves for optimal photosynthesis and to develop new shoots or flowers. This is essential for the plant's overall health and reproductive success. In the context of a plant's structure, nodes are vital for creating a branching pattern, which can significantly influence how effectively a plant captures sunlight and resources from its environment. While nodes may play a role in other processes, such as supporting the plant's growth and development, their primary purpose directly relates to the attachment and arrangement of leaves.
