Which of the following describes an anatomical difference between roots and leaves?

• A. Roots have a higher density of vascular bundles than leaves.
• B. Roots have stomata, while leaves do not.
• C. Roots lack chlorophyll, while leaves contain chlorophyll.
• D. Roots are covered with a cuticle, while leaves are not.

Answer: (C)

Verified step by step guidance

1. Identify the primary functions of roots and leaves in plants. Roots are primarily responsible for anchoring the plant and absorbing water and nutrients from the soil, while leaves are primarily involved in photosynthesis and gas exchange.
2. Understand the role of chlorophyll in plants. Chlorophyll is a pigment found in the chloroplasts of plant cells, and it is essential for photosynthesis, the process by which plants convert light energy into chemical energy.
3. Recognize that chlorophyll is typically found in the green parts of plants, such as leaves, where photosynthesis occurs. Roots, being underground, generally do not perform photosynthesis and therefore lack chlorophyll.
4. Consider the structural differences between roots and leaves. Leaves have a large surface area to maximize light absorption for photosynthesis, while roots are structured to penetrate the soil and absorb water and nutrients.
5. Evaluate the given options based on the understanding of plant anatomy and physiology. The correct statement is that roots lack chlorophyll, while leaves contain chlorophyll, as this aligns with the known functions and structures of these plant parts.
