What vascular plant tissue conducts water and dissolved mineral ions upward from the root system to the leaves through dead, lignified tracheary elements?
Answer and explanation
Correct answer: C. Xylem
- Step 1: Differentiate plant conducting tissues.
- Step 2: Xylem transports water and dissolved inorganic minerals upward via transpiration pull through hollow, dead cells (tracheids and vessel elements) reinforced with lignified secondary walls.
Answer
Xylem.
Why not the others: Phloem translocates organic sugars bi-directionally through living sieve tube elements; collenchyma and parenchyma provide structural support and storage.
