Cambium is a very important topic of biology and plant development. The topic is also important from an examination point of view. By studying cambium in detail, students will be able to compare the primary growth of plants with their secondary growth, describe the role of apical and lateral meristem in plant growth, and will be further able to compare between them. The students will also be able to perform a comparative study between the process and outcome of primary growth and secondary growth in stems and roots and will also be able to describe the function and organisation of woody stems that are derived from the secondary growth of plants.
