The correct Answer is:
To determine how many of the given statements are correct, we will analyze each statement one by one. 1. **Statement 1**: "Conjoint vascular bundles are not present in monocot stem." - **Analysis**: This statement is incorrect. In monocot stems, vascular bundles are indeed conjoint, meaning that xylem and phloem are located side by side within the same bundle. 2. **Statement 2**: "Casparian strips of endodermis are made of cutin." - **Analysis**: This statement is also incorrect. The Casparian strips in the endodermis are primarily made of suberin, and sometimes lignin, but not cutin. 3. **Statement 3**: "Pith is large and well developed in monocot roots." - **Analysis**: This statement is correct. In monocot roots, the pith, which is composed of parenchyma cells, is indeed large and well developed. 4. **Statement 4**: "Trichome helps in water loss due to transpiration." - **Analysis**: This statement is incorrect. Trichomes actually help to prevent water loss by reducing transpiration. They can also help in absorbing water and minerals. Now, let's summarize the correctness of each statement: - Statement 1: Incorrect - Statement 2: Incorrect - Statement 3: Correct - Statement 4: Incorrect **Conclusion**: Out of the four statements, only one statement (Statement 3) is correct. **Final Answer**: 1 statement is correct.
