💡 Key Idea
The Plant Body: A Modular System
Roots, stems, leaves—one coordinated system.
A flowering plant's body is organized into a root system (underground) and a shoot system (above ground). The shoot system comprises the stem, leaves, and flowers. Each organ has a specific function, but they work together for survival, growth, and reproduction.
↳ Morphology is the study of the external form and structure of these coordinated plant organs.

The Root System: Types and Functions
Taproot vs. fibrous—know the difference.
The root is the underground part of the plant. A taproot system has one main root with branches (e.g., mustard). A fibrous root system has many thin roots arising from the base (e.g., wheat). Roots anchor the plant and absorb water and minerals.
↳ Root systems are classified by their origin and branching pattern.
⭐ Important Fact
Root Modifications: Storage and Support
Roots do more than just absorb.
↳ Modified roots perform specialized functions like food storage and mechanical support.
