Quizplus · Accepted Answer

Cylindrical layers of meristem that run lengthwise through the shoots and roots are lateral meristems. They allow for thickening by adding more secondary tissues to the plant's organs. Apical meristems are located at the tips of roots and shoots, and they allow for primary growth in length. Ground meristem is a type of primary meristem that gives rise to ground tissue, while procambium is a type of primary meristem that gives rise to vascular tissue. The protoderm is another type of primary meristem that gives rise to the epidermis.
