Question

Fusiform initials form ?

• A. Vascular rays
• B. Tracheary elements
• C. Ray parenchyma
• D. Phloem parenchyma

Answer 1

The correct option is B Tracheary elements

The vascular cambium has thin walled cells of two types, the fusiform initials and the ray initials. The fusiform initials are the elongated cells that give rise to secondary xylem and secondary phloem. Additive division in these cells adds phloem/xylem mother cell that differentiates into their respective cell types. Tracheary elements are the fundamental elongated cell of xylem and are formed from fusiform initials.

Thus, the correct answer is option B.
