Vascular Cambium
The vascular cambium is a type of secondary growth tissue found in plants. It is a thin layer of cells that lies between the xylem and phloem, two key components of the plant's vascular system. This cambium is responsible for the growth in diameter of plant stems, enabling them to gain the added strength and flexibility needed for increased photosynthetic activity, for example. Its cells divide to form new xylem, which adds strength and rigidity to the stem, and phloem, which adds elasticity. The vascular cambium also helps to transport water and nutrients up and down the stem, increasing the plant’s ability to photosynthesize and survive in its environment. In short, the vascular cambium is necessary for the structural integrity and survival of the plant, and plays an important role in a plant’s ability to respond to environmental stimuli.
