The correct Answer is:
To solve the question, we need to analyze each statement regarding the anatomy of monocot and dicot leaves: ### Step-by-Step Solution: 1. **Statement (a): Palisade tissue is present towards the upper epidermis in monocot leaves.** - **Analysis**: In monocot leaves, the mesophyll tissue is typically uniform and does not differentiate into palisade and spongy layers as seen in dicots. Therefore, the palisade tissue is absent in monocot leaves. - **Conclusion**: This statement is **incorrect**. 2. **Statement (b): Lower layer of mesophyll cells is loosely packed with few chloroplasts in dicot leaves.** - **Analysis**: In dicot leaves, the mesophyll is differentiated into palisade and spongy layers. The lower layer (spongy mesophyll) is indeed loosely packed and contains fewer chloroplasts compared to the upper palisade layer. - **Conclusion**: This statement is **correct**. 3. **Statement (c): Dicot leaves have conjoint, collateral, and closed vascular bundles.** - **Analysis**: In dicot leaves, vascular bundles are typically arranged in a conjoint manner (xylem and phloem are found together) and are collateral (xylem is located on one side and phloem on the other). Additionally, they are closed, meaning there is no cambium present between them. - **Conclusion**: This statement is **correct**. ### Final Evaluation: - Statement (a) is incorrect. - Statement (b) is correct. - Statement (c) is correct. Thus, the correct answer is that only statement (a) is incorrect.
