2. Secondary growth produced by the cambium is bidirectional due to cells being added to both sides of the cambium layer. (target 2 of 6)
3. The vascular cambium generates xylem to the inside and phloem to the outside. (target 3 of 6, target 4 of 6)
4. The majority of cells added during secondary growth are parenchyma. (target 5 of 6)
5. The tissue that is commonly referred to as "wood" in a woody plant is composed of xylem formed from the vascular cambium.
