Question

Select the correct option:

Identify the types of vascular bundle in the figures (i) and (ii) and select the correct option.

(A) Conjoint collateral -	Conjoint bicollateral
(B) Conjoint bicollateral -	Conjoint collateral
(C) Conjoint collateral closed -	Conjoint collateral open
(D) Conjoint collateral open -	Conjoint collateral closed

• A. A
• B. B
• C. C
• D. D

Answer 1

The correct option is C C

The vascular bundle in figure i - is conjoint (xylem and phloem together), colateral (both present on the same axis) and closed (for secondary growth) because cambium is absent. Example, monocot stem.

The vascular bundle in figure ii - is also conjoint and colateral but shows presence of a cambial strip or vascular cambium in between xylem and phloem, hence it is open for secondary growth as in dicot stem.

So, the correct answer is 'C'
