Detailed explanation-1: -The lateral meristem tissues are responsible for the secondary growth of plants.
Detailed explanation-2: -Secondary growth results in increase in girth or diameter of the stem by formation of secondary tissue by the activity of lateral meristem. So for study of secondary growth, teak (angiosperm) and pine (gymnosperm) are best suited. In wheat, fern and sugarcane there is no secondary growth. So, option C is correct.
Detailed explanation-3: -Secondary growth is the outward growth of the plant, making it thicker and wider. Secondary growth is important to woody plants because they grow much taller than other plants and need more support in their stems and roots. Lateral meristems are the dividing cells in secondary growth, and produce secondary tissues.
Detailed explanation-4: -Collenchyma. Collenchyma cells have thick walls that are especially thick at their corners. These cells provide mechanical support for the plant.
