How water moves from one place to another in a plant By Umema Khan 8C
Task Water enters the root (often well below the soil surface) and much of it ends up at the leaves, which in some tree species can be up to 100 metres above ground level. How many of us have stopped to consider just how this movement is achieved? The answer is, that a variety of forces and processes are involved.
It all starts with the roots Most of the water absorption is carried out by the younger part of the roots. Just behind the growing tip of a young root is the pilferers region, made up of hundreds of projections of the epidermal tissue, the root hairs
Next Step… Once inside the root hair, the water needs to be transferred to the xylem, the vascular tissue involved in water transport through the plant. In roots, the vascular tissue is found in a central column, separated from the cortex parenchyma cells by a single layer of cells called the endodermis
Last but not least After it travels through the xylem to the stem and leaves then is used for the plant’s needs.
