The correct Answer is:
To determine which statement is false about monocot stems, we will analyze each option one by one: ### Step-by-Step Solution: 1. **Statement I**: "Vascular bundles - scattered, conjoint, close, surrounded by sclerenchymatous bundle sheath and with water cavity." - **Analysis**: This statement is true. In monocot stems, vascular bundles are indeed scattered throughout the ground tissue, they are conjoint (xylem and phloem are found together), and they are closed (lacking cambium). The presence of a sclerenchymatous bundle sheath and water cavities is also characteristic of monocot stems. 2. **Statement II**: "Hypodermis is sclerenchymatous." - **Analysis**: This statement is also true. The hypodermis in monocot stems is typically made up of sclerenchyma, which provides structural support. 3. **Statement III**: "Peripheral vascular bundles - Smaller than centrally placed ones." - **Analysis**: This statement is true as well. In monocot stems, the vascular bundles located peripherally are generally smaller compared to the larger, centrally located vascular bundles. 4. **Statement IV**: "Ground tissue is differentiated into cortex, pericycle, pith, etc." - **Analysis**: This statement is false. In monocot stems, the ground tissue is not differentiated into distinct regions like cortex, pericycle, and pith. Instead, it is typically homogeneous and consists mainly of parenchyma. 5. **Statement V**: "Homogeneous parenchymatous ground tissues." - **Analysis**: This statement is true. Monocot stems primarily have a homogeneous ground tissue composed of parenchyma cells. ### Conclusion: The false statement about monocot stems is **Statement IV**: "Ground tissue is differentiated into cortex, pericycle, pith, etc."
