Hyponatremia is a condition where the concentration of sodium is abnormally low in the body. Sodium acts as an electrolyte that helps in maintaining the amount of water in the body.
Extremely low amount of sodium in the body leads to weakness, headache, etc. During periods of intense activity body releases vasopressin hormone that helps body to retain water. Endurance athletes become vulnerable to developing hyponatremia because these athletes during water during strenuous exercises.

Answer:
The correct answer will be- endoplasmic reticulum
Explanation:
Plasmodesmata are the cytoplasmic bridges spanning in the cell walls of the plant cell which link the cytoplasm of the adjacent cells. The plasmodesmata play an important role in the plants as they allow the inter-cellular connections between the cells.
The plasmodesmata are derived from the juxtaposed endoplasmic reticulum which forms the axial or the central portion of the plasmodesmata and allows the transport of molecules between two cells.
Thus, the endoplasmic reticulum is the correct answer.
