The correct Answer is:
To solve the question, we need to evaluate each of the provided statements about leaves and determine their correctness. ### Step-by-Step Solution: 1. **Evaluate Statement (a)**: - "Simple leaves have bud on the axis of the petiole." - In botany, a simple leaf is characterized by having a single blade and a petiole. The bud is indeed located in the axil of the petiole, where the leaf attaches to the stem. - **Conclusion**: This statement is **correct**. 2. **Evaluate Statement (b)**: - "In pinnately compound leaf, the midrib forms a common axis called rachis." - A pinnately compound leaf consists of multiple leaflets arranged along a central axis. The midrib of the leaf extends into the rachis, which is the continuation of the midrib that supports the leaflets. - **Conclusion**: This statement is **correct**. 3. **Evaluate Statement (c)**: - "Paripinnate leaves are found in Cassia." - Paripinnate leaves are characterized by having an even number of leaflets, which are arranged symmetrically on either side of the rachis. Cassia is known to have paripinnate leaves. - **Conclusion**: This statement is **correct**. 4. **Evaluate Statement (d)**: - "Tripinnate leaves are found in Mimosa." - Tripinnate leaves have leaflets that are further divided into smaller leaflets, and Mimosa (specifically Mimosa pudica, also known as the touch-me-not plant) is known to have tripinnate leaves. - **Conclusion**: This statement is **correct**. ### Final Conclusion: All four statements (a, b, c, and d) are correct.
