Identify the incorrect one

Options

A. All leaves have buds in their axils
B. Buds are absent in leaf-let axil
C. Simple leafhas undivided lamina
D. Compound leaves have incompletely divided lamina

Answer

To identify the incorrect statement among the options provided, we can analyze each option step by step:

1. **First Option: All leaves have buds in their axil.**
- **Analysis:** This statement is correct. In botany, the axil is the angle between the upper side of a leaf or stem and the supporting stem or branch. Typically, buds are found in the axils of leaves, which can develop into new shoots or flowers.
- **Conclusion:** This option is correct.

2. **Second Option: Buds are absent in leaflet axil.**
- **Analysis:** This statement is also correct. Leaflets are the individual segments of a compound leaf. In a compound leaf, the axil of each leaflet does not contain a bud, as the leaflets are already divided and do not support the formation of new buds.
- **Conclusion:** This option is correct.

3. **Third Option: Simple leaves have undivided lamina.**
- **Analysis:** This statement is correct. Simple leaves consist of a single, undivided lamina (the flat part of the leaf). They do not have any subdivisions or leaflets, which is why they are termed 'simple.'
- **Conclusion:** This option is correct.

4. **Fourth Option: Compound leaves have incomplete divided lamina.**
- **Analysis:** This statement is incorrect. Compound leaves are characterized by having a lamina that is divided into multiple leaflets, but the lamina itself is considered complete. The term "incomplete" suggests that the lamina is not fully developed, which is misleading. The lamina of a compound leaf is complete, even though it is divided into smaller parts.
- **Conclusion:** This option is incorrect.

**Final Answer:** The incorrect statement is: "Compound leaves have incomplete divided lamina."
