Correct Option
The correct option is (c) 1 and 3 only.
Explanation
Plants possess a specialized vascular system for the transportation of nutrients and water. This system consists of pipe-like vessels made of specialized cells, forming the vascular tissue known as xylem for water and minerals, and phloem for food.
Statement-wise Analysis
- Statement 1 is Correct: Roots are the primary organs responsible for absorbing water and minerals from the soil. They possess root hairs which significantly increase the surface area of the root for the absorption of water and mineral nutrients dissolved in water.
- Statement 2 is Incorrect: The transport vessels are not restricted to the roots. These vessels extend from the roots, upward through the stem, and into the branches and leaves to ensure the delivery of water to all parts of the plant.
- Statement 3 is Correct: The vessels (specifically xylem tracheids and vessels) form a continuous network of channels that connects roots to the leaves through the stem and branches. This continuous path ensures that water and nutrients are efficiently transported throughout the entire plant system.
Key Takeaway
Xylem forms a continuous, interconnected network of channels extending from the roots through the stem to the leaves, facilitating the unidirectional transport of water and minerals.
