C. Monocot stem
Secondary growth, also known as lateral growth or increase in girth, is absent in monocot stems. Monocots typically lack the vascular cambium and cork cambium that are responsible for secondary growth in dicot stems and roots. Secondary growth results in the thickening of stems and roots, leading to the development of woody tissues and increased girth over time. In contrast, dicot stems, dicot roots, and gymnosperms are capable of undergoing secondary growth.
