NEET BIOLOGY

Detailed explanation-1: -Water and solutes are transported by the xylem from the roots to the leaves, and food is transported from the leaves to the rest of the plant by the phloem.

Detailed explanation-2: -The xylem is a tissue which transports water and minerals from the roots up the plant stem and into the leaves.

Detailed explanation-3: -The path taken is: soil-> roots-> stems-> leaves. The minerals (e.g., K+, Ca2+) travel dissolved in the water (often accompanied by various organic molecules supplied by root cells). Water and minerals enter the root by separate paths which eventually converge in the stele, or central vascular bundle in roots.

Detailed explanation-4: -In plants, water and minerals are transported through xylem cells from soil to the leaves. The xylem cells of roots, stems and leaves are interconnected to form a conducting channel that reaches all parts of the plant body. The root cells take ions from the soil.

Detailed explanation-5: -Cohesion-tension essentially combines the process of capillary action with transpiration, or the evaporation of water from the plant stomata. Transpiration is ultimately the main driver of water movement in xylem.
