Questions and their answers

Questions and their answers 1. Question: What is the defining feature of a dicot root's vascular bundle arrangement? Answer: The vascular bundles are arranged radially, with the xylem forming a star-shaped pattern in the center. 2. Question: How does the pith of a monocot root differ from that of a dicot root? Answer: A monocot root has a large, well-developed pith, while a dicot root has a small or absent pith. 3. Question: In a dicot stem, what is the specific term for the arrangement of vascular bundles? Answer: The vascular bundles are arranged in a ring. 4. Question: Why are the vascular bundles in a monocot stem described as "closed"? Answer: They are closed because they lack cambium, which means they cannot undergo secondary growth. 5. Question: What is the primary function of collenchyma cells in a dicot stem's hypodermis? Answer: They provide mechanical support to the young, growing stem. 6. Question: What is the main structural difference in the mesophyll of...
