Summary

This section explores the architecture and growth of plants, covering key topics such as carbon sequestration by long-lived trees, the organization of plant tissue systems (dermal, vascular, and ground tissues), and the dynamics of primary and secondary growth. It also highlights the differences between monocots and eudicots in terms of tissue arrangement and explains how tree rings can provide valuable climatic and historical information.
