Quizplus · Accepted Answer

Lateral meristems, also known as secondary meristems, are responsible for the secondary growth of plants, which involves increasing the width or girth of the plant. One type of lateral meristem is the vascular cambium, which is responsible for producing the cylindrical layers of meristem that run lengthwise through shoots and roots and allow for thickening. Apical meristems are responsible for the primary growth of plants, which involves increasing the length of the plant. Ground meristem and protoderm are both types of primary meristem, which give rise to various types of plant tissues. The procambium is a type of primary meristem that gives rise to the vascular tissue system.
