Question

Jeremy is observing a cross-section of a corn stem under the microscope. He observes that there is no vascular cambium present in this stem. Why is there no vascular cambium in corn stems?

Answer 1

Answer:

Vascular cambium  is not present in monocots.

Explanation:

Vascular cambium  is the tissue responsible for secondary growth. It leads to development of secondary vascular tissues during secondary growth. Secondary growth and presence of vascular cambium  is a feature of dicotyledonous plants only. Since corn is a monocotyledous plant, it does not have vascular cambium.

Answer 2

Vascular cambium is a the tissue which is present in between the xylem and phloem. Te cells of vascular cambium divide to form secondary vascular structure, which is not a feature of the monocots like corn. Secondary vascular structures are true to dicots and do not carry water or minerals, rather increase thickness of the plant.
