- Explain why the vascular cambium forms acontinuous sheath that runs from near the tips of thebranches to near the tips of the roots, whereas the corkcambium is discontinuous in both space and time.Plant B grows in unstable soil, it also needs to grow rather tall and grow quickly. This results in a tall, thin plant, grows, reproduces and dies in one year. What type of root adaptaion might it have, and what kind of life cycle would it have (use the plant terminology for life cycles)? Stolons and biennial life cycle Fiberous roots and annual life cycle O Prop roots and annual life cycle Prop roots and indeterminate growthCompare the leaf structure of Nerium to Ligustrum. Look for stomata. Where are they located? On the upper or lower leaf surface? How is the surface of the leaf modified? Can you recognize why these leaves are said to have “sunken stomata”?
