The correct option is (c).
Explanation
Vascular plants possess specialized conducting tissues for the transport of materials. The xylem is responsible for the transport of water and minerals, while the phloem transports organic nutrients (food). This vascular system forms a continuous network throughout the plant body.
Statement-wise Analysis
- Statement 1 is Incorrect. Water and minerals are primarily absorbed by the roots, not the leaves. The root hair cells increase the surface area of the root system, facilitating the absorption of water and dissolved mineral nutrients from the soil through diffusion and osmosis. Leaves are primarily responsible for photosynthesis and transpiration.
- Statement 2 is Correct. Once absorbed by the roots, water and minerals are transported upward to the leaves and other parts of the plant through a specialized tissue called the xylem. The xylem consists of vessels and tracheids which serve as the conduits for this transport.
- Statement 3 is Correct. The xylem vessels and tracheids form a continuous, interconnected system of tubes. This network runs from the roots, up through the stem and branches, and into the leaves, ensuring a steady supply of water and minerals to all aerial parts of the plant.
Key Takeaway
Xylem tissue forms a continuous channel connecting roots to leaves for the unidirectional transport of water and minerals, whereas roots are the primary site for absorption from the soil.
