Which one of the following best describes the symplast pathway of water flow from the epidermis to endodermis in a plant root?
Water moves through cell walls and extracellular spaces without crossing any membrane.
Water travels across the root cortex via the plasmodesmata.
Water crosses the plasma membrane of each cell in its path twice, once on entering and once on exiting.
Transport across the tonoplast.
Answers (1)
In the symplast pathway, water moves through the interconnected cytoplasm of plant cells, facilitated by plasmodesmata. Plasmodesmata are specialized channels that allow for the transport of water and solutes between adjacent plant cells. These channels connect the cytoplasm of neighboring cells, creating a continuous symplastic network throughout the root cortex.
Water enters the root epidermis and then moves from cell to cell through the plasmodesmata, traversing the root cortex. This symplastic pathway allows for the movement of water and solutes through the living components of the root, including the cortex cells, before reaching the endodermis.
Therefore, option b is the best description of the symplast pathway of water flow from the epidermis to the endodermis in a plant root. Hence, the correct answer is option 2.
