Which of the following is NOT a function of the vascular cambium?

The vascular cambium is a crucial meristematic tissue in plants that plays a key role in secondary growth. It is responsible for producing new cells that contribute to the growth in thickness of the stems and roots. The cambium divides to form xylem cells towards the inside of the plant and phloem cells towards the outside, which are essential for water and nutrient transport, respectively. It also contributes to the formation of new bark by producing additional layers of phloem.

Photosynthesis, however, is a process carried out primarily by chloroplasts found in leaf tissues, where sunlight is captured to convert carbon dioxide and water into glucose and oxygen. The vascular cambium does not engage in photosynthesis; rather, it focuses on growth and development in the plant's vascular system. Therefore, it is accurate to state that photosynthesis is not a function of the vascular cambium.
