Which of the complying with statements around the vascular cambium is true? 1. It is a layer of undifferentiated cells that develops right into second xylem and phloem. 2. It is a type of apical meristem. 3. It is located between the primary xylem and also cortex. 4. It establishes into cork cells on the outside of the cortex.
Why perform plants need additional growth? 1. To provide structural support for the plant 2. To produce a much more extensive root system 3. To thrive taller 4. To produce brand-new leaves
