The correct option is A-1, B-3, C-4, D-2
Explanation
Plants exhibit various physiological processes and morphological features essential for their survival, growth, and transport of nutrients. These include mechanisms for food synthesis, water regulation, and structural organization.
Detailed Analysis:
- A. Process of making food - Photosynthesis (1): Photosynthesis is the physicochemical process by which green plants use light energy to drive the synthesis of organic compounds (food) from carbon dioxide and water. It primarily occurs in the chloroplasts of leaves.
- B. Loss of water as vapour - Transpiration (3): Transpiration is the evaporative loss of water from the aerial parts of the plant, mainly through stomata in the leaves. This process creates a suction pull that aids in water transport.
- C. Movement of water in stem - Conduction (4): Conduction refers to the upward movement of water and dissolved minerals from the roots to the stem and leaves. This transport is facilitated by vascular tissues, specifically the xylem.
- D. Design of veins in leaf - Venation (2): Venation is the arrangement of veins and veinlets in the lamina of a leaf. It provides structural support and facilitates the transport of water and nutrients. Common types include reticulate and parallel venation.
Conclusion:
Based on the definitions above, the correct matching is A-1, B-3, C-4, D-2.
Key Takeaway:
Plant biology distinguishes between metabolic processes like photosynthesis, physiological transport mechanisms like transpiration and conduction, and anatomical features like venation.
