Anatomy Of Flowering Plants Question 17
Question: What happens in plants during vascularisation?
Options:
A) Differentiation of procambium, formation of primary phloem followed by formation of primary xylem.
B) Differentiation of procambium followed by the formation of primary phloem and xylem simultaneously.
C) Formation of procambium, primary phloem and xylem simultaneously.
D) Differentiation of procambium followed by the formation of secondary xylem.

Answer:
Correct Answer: B
Solution:
The correct option is B
Differentiation of procambium followed by the formation of primary phloem and xylem simultaneously
Procambium lies just inside the protoderm. Procambium develops into primary xylem and primary phloem.
It also forms vascular cambium (which further forms secondary xylem and secondary phloem), cork cambium (forms periderm).
This whole process is known as vascularisation of plants. Thus, option B is correct.
