Unit 3035: Plant Anatomy and Morphology

1. Introduction to Plant Anatomy and Morphology

• Overview of plant structure and form
• Major plant parts: roots, stems, leaves, flowers, fruits, seeds
• Functions of different plant parts

2. Plant Cells and Tissues

• Types of plant cells: parenchyma, collenchyma, sclerenchyma
• Specialized cells and their functions
• Plant tissues: dermal, ground, vascular
• Tissue organization and role in plant structure and function

3. Root Structure and Function

• Anatomy of roots: root hairs, root cap, zones of growth
• Vascular tissues in roots (xylem and phloem)
• Mechanisms of water and nutrient absorption
• Root adaptations and symbiotic relationships

4. Stem Anatomy and Growth

• Stem structure: epidermis, cortex, vascular bundles, pith
• Growth patterns: primary and secondary growth
• Differences between herbaceous and woody stems
• Functions of stems in support and transport

5. Leaf Morphology and Photosynthesis

• Leaf structure: blade, petiole, veins
• Leaf adaptations (e.g., xerophytes, hydrophytes)
• Internal leaf anatomy: mesophyll, stomata
• Photosynthesis process overview and leaf role in energy production

6. Flower Structure and Reproduction

• Anatomy of flowers: sepals, petals, stamens, carpels
• Pollination mechanisms: self-pollination, cross-pollination, biotic and abiotic agents
• Sexual reproduction in plants: fertilization and seed formation

7. Fruit Development and Seed Dispersal

• Fruit anatomy and types
• Seed formation and structure
• Methods of seed dispersal: wind, water, animals, mechanical
• Importance of dispersal for plant propagation

8. Plant Adaptations to Environmental Factors

• Structural and morphological adaptations to deserts, forests, aquatic habitats
• Examples: succulence, leaf modifications, root adaptations
• Survival strategies under environmental stress

9. Plant Growth Regulators

• Overview of plant hormones: auxins, gibberellins, cytokinins, ethylene, abscisic acid
• Roles in growth, development, and environmental response
• Practical applications in agriculture and horticulture

10. Comparative Plant Anatomy

• Comparative analysis of monocots vs dicots
• Anatomical diversity among plant species
• Evolutionary significance of anatomical features
• Case studies highlighting diversity and adaptation
