A set of xylem tissues are:
Correct answer: A. Vessels, tracheids, parenchyma
- A. Vessels, tracheids, parenchyma
- B. Sieve tubes, companion cells, fibers
- C. Parenchyma, sieve tube, vessels
- D. Fibers, companion cells, tracheids
Explanation
Xylem tissue is primarily responsible for water transport in plants and consists of four main components: tracheids, vessels, parenchyma, and fibers. Option A correctly lists these components. The other options include elements that belong to phloem tissue, such as sieve tubes and companion cells, which are involved in the transport of nutrients.

About Plant Nutrition and Transport
Plants require macronutrients and micronutrients for growth, and mineral deficiencies produce recognizable symptoms. Transport involves water and minerals through xylem by transpiration pull, cohesion and adhesion, while phloem translocates sugars from sources to sinks. Root pressure and transpiration are distinct mechanisms.
