To solve the problem, we need to identify the structure in a plant through which water is transported.
1. Understanding Plant Transport Systems:
In plants, there are two primary transport systems: the xylem and the phloem. These systems are responsible for the movement of different substances throughout the plant.
2. Role of Xylem:
- Xylem is a vascular tissue that transports water and dissolved minerals (such as nutrients) from the roots to the leaves and other parts of the plant. It consists of dead cells, including tracheids and vessel elements, which form a continuous network of tubes.
3. Role of Phloem:
- Phloem, on the other hand, is responsible for transporting organic substances (such as sugars produced during photosynthesis) from the leaves to other parts of the plant, including the roots. It consists of living cells called sieve tube elements and companion cells.
4. Role of Medulla:
- Medulla refers to the inner part of certain plant structures, such as the stem or root. While it may play some role in supporting the plant, it is not directly involved in the active transport of water.
5. Identifying the Correct Answer:
Water is primarily transported through the xylem in plants. The xylem forms a continuous pathway from the roots to the leaves, allowing water and dissolved minerals to move upward against gravity.
6. Conclusion:
The correct answer is (A) Xylem.
