The correct Answer is:
### Step-by-Step Solution: 1. **Identify the Types of Leaves**: The question refers to different types of leaves and how they receive sunlight. The types mentioned include unifinate leaves, palmately compound leaves, isobilateral leaves, and dorsi-ventral leaves. 2. **Understand Leaf Structure**: - **Unifinate Leaves**: Leaflets are directly attached to the midrib, often in opposite or sub-opposite pairs. - **Palmately Compound Leaves**: Leaflets radiate from a short midrib, resembling fingers on a hand. - **Isobilateral Leaves**: Both the upper and lower surfaces of the leaf are similar. - **Dorsi-Ventral Leaves**: These leaves have distinct upper (dorsal) and lower (ventral) surfaces. 3. **Analyze Sunlight Reception**: - Sunlight is crucial for photosynthesis, and the way leaves are structured affects how they receive sunlight. - **Isobilateral Leaves**: These leaves are oriented parallel to the main axis and to the sun's rays, allowing them to receive sunlight evenly on both sides. 4. **Conclusion**: Based on the analysis, isobilateral leaves are the type that receives an equal amount of sunlight on all sides due to their structural orientation. ### Final Answer: Equal amounts of sunlight are received on all sides by **isobilateral leaves**. ---
