Question

In a transverse section of a monocot stem, vascular bundles are described as 'closed'. What does this term signify?
Options
A They are tightly packed together.
B They are surrounded by a vascular cambium.
C They lack a cambium and cannot produce secondary tissue.
Correct Answer
D They are enclosed within a sclerenchymatous bundle sheath.
Correct Answer

Option C is the correct answer.

Detailed Explanation

The text in section 2.5 Stem Anatomy in Detail states: "The bundles are described as 'closed' because they lack a cambium and cannot produce secondary tissue." Option D describes an associated characteristic but not the meaning of 'closed' bundles.

Hint

Consider what 'secondary thickening' implies and what tissue is responsible for it in dicots.
