Study Notes
Plant Morphology and Anatomy Overview
- Course focuses on structures and functions of flowering plants, the highest group of land plants.
- Plant bodies consist of various organs; emphasis on morphology and its biological relevance.
Fundamentals of Morphology
- Morphology studies the structures and forms of plant bodies, including both external and internal aspects.
- External morphology covers visible structures, while internal morphology involves hidden structures.
Importance of Plant Morphology and Anatomy
- Provides foundational knowledge for other biological sciences courses.
- Essential for identifying and classifying flowering plant species.
- Contributes to the understanding of the origin and evolution of flowering plants.
- Serves as a basis for applied science programs like forestry, agriculture, and pharmacology.
Structure of a Plant Body
- Composed of two main systems: shoot and root systems.
- Shoot System: Includes stems, leaves, flowers, and fruits.
- Root System: Comprised of primary, secondary, and tertiary roots.
Understanding Plant Habit
- Defined as the general form or appearance of plants, including size, height, woodiness, and stem branching patterns.
- Different types of plant habits in flowering plants include herbs, shrubs, trees, vines, and lianas.
Examples of Plant Habits
- Herbs: Crotalaria retusa, Commelina species, Grasses, Talinum triangulare (Waterplant), Tridax procumbens, Ageratum conyzoides (Goatweed).
- Shrubs: Hibiscus species, Ixora species, Ricinus communis (Castor Oil).
- Trees: Ceiba pentandria (Silk Cotton Tree), Cocos nucifera (Coconut Palm), Terminalia superba.
- Vines: Ipomoea batatas (Sweet Potato), Dioscorea species (White Yam), Momordica charantia (Bitter Lemon).
- Lianas: Combretum species, Landolphia species.
Revision
- Revision questions included to reinforce understanding of plant morphology, habit, and life form.
