Question:
Which one of the following is vascular tissue?
Which one of the following is vascular tissue?
Show Hint
The vascular tissue system in plants consists of two complex tissues:
- Xylem: Transports water and minerals upward.
- Phloem: Translocates organic photosynthates downward and bidirectionally.
- Xylem: Transports water and minerals upward.

The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Plant tissues are structurally and functionally organized into three major tissue systems: dermal tissue (outer protective covering), ground tissue (photosynthesis, storage, and support), and vascular tissue (long-distance transport of water and nutrients).
Step 2: Detailed Explanation:
Let us analyze each tissue type:
- Xylem (3): A complex, specialized vascular tissue responsible for conducting water and dissolved mineral nutrients upward from the roots to the shoots. It consists of tracheary elements (vessels and tracheids), xylem parenchyma, and sclerenchyma fibers. It is a key vascular tissue.
- Collenchyma tissue (1): A simple support tissue made of living cells with unevenly thickened primary cell walls, providing flexibility and mechanical support to growing organs. It is a ground tissue.
- Epidermal tissue (2): The single outer layer of cells covering the entire plant body, serving protective, barrier, and gas exchange functions. It is a dermal tissue.
- Palisade parenchyma (4): Columnar, chloroplast-rich cells located in the upper mesophyll layer of leaves, optimized for light absorption during photosynthesis. It is a ground tissue.
Therefore, xylem is the only option classified as a vascular tissue.
Step 3: Final Answer:
The vascular tissue is X Xylem.
