______ is the water transporting tissue in plants. |
Cortex Xylem Stele Phloem |
Xylem |
The correct answer is Option (2) -Xylem Xylem is a complex tissue found in vascular plants, responsible for the transportation of water and minerals from the roots to the rest of the plant. It is composed of several types of cells, including vessel elements, tracheids, fibers, and parenchyma cells. Vessel elements and tracheids are the main water-conducting cells in xylem. They are elongated cells with thick, lignified cell walls that provide structural support and prevent collapse under pressure. In addition to water and minerals, xylem also transports dissolved nutrients and hormones throughout the plant. The movement of water through xylem is primarily driven by transpiration, the process by which water evaporates from the leaves, creating a negative pressure that pulls water up through the plant. Overall, xylem plays a crucial role in maintaining the water balance and structural integrity of vascular plants. |
