Question

Which of the following is an example of complex tissue? ____.

• A. Xylem
• B. Phloem
• C. Both A & B
• D. Collenchyma

Hint:

Think of it like a work team. A Simple tissue is a group of identical workers doing the same job. A Complex tissue is a diverse project team (different looking cells) working together toward one common goal (like fluid transport).

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Plant tissues are structurally divided into simple tissues (made of only one type of cell) and complex tissues (made of multiple types of cells working together as a unit).

Step 2: Detailed Explanation:
Both Xylem and Phloem are classic examples of complex permanent tissues:
• Xylem consists of four distinct cellular components: tracheids, vessels, xylem parenchyma, and xylem fibers. It primarily transports water and dissolved minerals upward from roots to leaves.
• Phloem consists of sieve tubes, companion cells, phloem parenchyma, and phloem fibers. It transports prepared organic food materials from leaves to other parts of the plant.
• Collenchyma is a simple permanent tissue made up of only one cell type.

Step 3: Final Answer:
Both xylem and phloem are complex tissues, making (C) the correct option.
