Which of the following statements is incorrect regarding the transverse section of a typical dicotyledonous stem?

Options

  1. AThe innermost layer of the cortex is called the endodermis, and its cells are rich in starch grains.
  2. BThe pericycle is present on the inner side of the endodermis and above the phloem in the form of semi-lunar pa
  3. CThe vascular bundles are conjoint, open, and arranged in a characteristic ring.
  4. DThe ground tissue is an undifferentiated mass of loosely arranged parenchyma cells.

Correct answer

D. The ground tissue is an undifferentiated mass of loosely arranged parenchyma cells.

Step-by-step solution

In a typical dicotyledonous stem, the ground tissue is well-differentiated into distinct regions: the cortex (hypodermis, general cortex, and endodermis), pericycle, medullary rays, and pith. The endodermis is often referred to as the starch sheath, and the pericycle occurs as semi-lunar patches of sclerenchyma above the phloem.
