Detailed explanation-1: -Primary school students are required to know that the stem contains food-carrying tubes (phloem tubes) and water-carrying tubes (xylem tubes).
Detailed explanation-2: -When the food-carrying tubes are removed, food made by the leaves will not be able to be transported to other parts of the plant. This causes the food to accumulate at the cut, which results in the bulging of the stem.
Detailed explanation-3: -There are tubes for transporting water and food in plants. The water-carrying tubes are called xylem. They transport water and dissolved substances from the roots to all parts of a plant. The food-carrying tubes are called phloem.
Detailed explanation-4: -The stem is the part of the plant responsible for conducting water. Within the stem, there is a structure called xylem which forms a network of tubes which carry water from the roots to all parts of the plant.
