Solution

The correct option is D Two
  • Casuarina is a genus of oak tree species belonging to the family Casuarinaceae.

  • They are also known as ironwoods.

  • All the cells in the structure of roots can be traced back to few apical cells which are called initials.

  • In Casuarina, only two rows of initials are observed at the root apex.

  • One of the layers gives rise to the stele and the other to the cortex and root cap.

  • So, the correct answer is 'Two'.
