Which structure is associated with Apiaceae in this material?

• A. Parenchymal Cells
• B. Glandular Trichomes
• C. Vittae
• D. Schizogenous Ducts

Answer: (C)

Vittae are oil-containing secretory ducts that are a characteristic feature of Apiaceae. In this family, essential oils are stored in these elongated cavities within the parenchyma of stems, leaves, and especially the fruit pericarp. Under a microscope, you’d see these ducts as distinct oil-filled spaces surrounded by secretory cells, which is why they’re commonly used as a diagnostic structure for Apiaceae. Parenchymal cells are generic plant cells without this secretory specialization. Glandular trichomes are surface structures that secrete oils in many plants but aren’t a defining feature of Apiaceae. Schizogenous ducts are a different type of secretory duct formation, not the distinctive trait highlighted for Apiaceae in this context.
