The correct Answer is:
To solve the question regarding the statements about leaflets of a compound leaf, we need to analyze each option carefully: 1. **Understanding Leaflets of Compound Leaves**: - A compound leaf consists of multiple leaflets attached to a single petiole. Each leaflet is a separate blade. 2. **Evaluating Each Statement**: - **(a) They are always borne laterally in one plane**: - This statement is not entirely correct. While many leaflets are arranged in a single plane (pinnate or palmate arrangements), they can also be arranged in different orientations depending on the species. - **(b) They do not bear axillary bud**: - This statement is correct. In a compound leaf, the leaflets do not have axillary buds at their base. Instead, the axillary bud is located at the base of the entire compound leaf. - **(c) They bear stipules at base**: - This statement can be misleading. While some compound leaves may have stipules, it is not a universal characteristic of all compound leaves. Therefore, this statement is not necessarily correct for all cases. - **(d) They may arise at the tip of petiole**: - This statement is incorrect. Leaflets do not arise at the tip of the petiole; they are typically attached along the length of the petiole. 3. **Conclusion**: - The correct statement about leaflets of a compound leaf is **(b) They do not bear axillary bud**. ### Step-by-Step Solution: 1. **Identify the nature of compound leaves**: Understand that compound leaves consist of multiple leaflets. 2. **Analyze each statement**: Evaluate the truthfulness of each statement regarding leaflets. 3. **Determine the correct statement**: After analysis, conclude that statement (b) is correct.
