Study Notes
Overview of Angiosperm Morphology
- Angiosperms, or flowering plants, exhibit a diverse range of external structures, collectively referred to as morphology.
- Fundamental components of angiosperms include roots, stems, leaves, flowers, and fruits.
Importance of Classification and Terminology
- Understanding morphological characteristics is essential for classifying higher plants.
- Familiarity with standard technical terms and definitions aids in recognizing variations due to adaptations to different environments.
- Adaptations may include features for protection, climbing, and storage.
Plant Structure
- The root system is the underground part of flowering plants, while the shoot system is the portion above ground.
- Common weeds demonstrate the presence of roots, stems, and leaves, with flowering and fruiting capabilities.
The Root System
- In dicotyledonous plants, the primary root begins from the elongation of the radicle and grows into the soil.
- The primary root develops lateral roots, categorized into secondary, tertiary, etc., contributing to the root hierarchy.
