Which of the following correctly differentiates xylem vessels from tracheids?
hard Q10 of 15
Step-by-Step Solution
Step 1: Understand structure and function of vessels and tracheids
The question asks for correct differences between xylem vessels and tracheids.Step 2: Analyze options based on botanical facts
Vessels are long, narrow cells with tapered ends; tracheids are short and wide with perforations. is incorrect because vessels are wide and short with perforated end walls, tracheids are long and narrow with tapered ends; Vessels have perforated end walls forming continuous tubes; tracheids lack perforations and conduct water through pits. is correct as vessels have perforated end walls forming continuous tubes, while tracheids lack perforations and conduct water through pits; Both vessels and tracheids have perforated end walls and conduct food. is wrong because they conduct water, not food; Tracheids are living cells; vessels are dead cells. is incorrect as both vessels and tracheids are dead cells.Final Answer:
Vessels have perforated end walls forming continuous tubes; tracheids lack perforations and conduct water through pits. → Option BQuick Check:
Xylem vessels vs tracheids = Perforated tubes vs pits ✅
Quick Trick: Vessels = perforated tubes; Tracheids = water conduction via pits.
Common Mistakes:
- Confusing vessels and tracheids structure and function.
