the spongy tissue found inside the stems and branches of plants
The pith refers to the spongy, central tissue found in the stems, branches, and sometimes the cores of certain plants. It is composed of parenchyma cells and serves various functions, including storing and transporting water, nutrients, and sugars throughout the plant. In stems and branches, the pith provides structural support and helps maintain the plant's rigidity. In some fruits, such as citrus fruits like oranges and lemons, the pith is also found surrounding the edible segments, although it is often bitter and less desirable for consumption compared to the juicy flesh. Additionally, the pith can play a role in insulation, protecting the plant from extreme temperatures.
