उत्तर
Process of ascent of sap in plants occurs by xylem.
Explanation:
The ascent of sap is the upward movement of water and dissolved mineral nutrients from the roots to the leaves against gravity. This process occurs exclusively through the dead, hollow tube-like elements of the xylem tissue, driven by driving forces like transpiration pull and root pressure. In contrast, phloem is responsible for distributing manufactured organic food, while the cortex assists in lateral transport and the cambium manages growth.
