What type of cambium is involved in secondary growth in plants?

The vascular cambium is specifically responsible for secondary growth in plants. This type of cambium is a layer of meristematic tissue that produces new xylem (wood) and phloem (bark) cells as the plant grows. This process allows for an increase in the girth of the plant stems and roots, contributing to the overall increase in the plant's size and the formation of woody tissue.

The vascular cambium is located between the xylem and phloem, allowing it to facilitate the transport of water, nutrients, and food throughout the plant as it expands. The secondary growth produced by the vascular cambium is crucial for the development of many types of plants, particularly dicotyledons and gymnosperms, which rely on this growth to support larger structures and enhance stability.

Other types of cambium mentioned, such as intercalary cambium and fascicular cambium, play different roles in plant growth and do not primarily contribute to secondary growth. Intercalary cambium is associated with the elongation of internodes and involved in primary growth, usually found in monocots. Fascicular cambium refers to the cambium found within the vascular bundles and is more limited in its function compared to the vascular camb
