Question

Interfascicular cambium develops from cells of.

• A. Pericycle
• B. Medullary rays
• C. Xylem parenchyma
• D. Endodermis

Answer 1

The correct option is B Medullary rays

In the dicot stem, during intra stelar secondary growth, two types of cambia are formed. A strip of cambium formed between the xylem and phloem of a vascular bundle is called Intra fascicular cambium. Another strip of cambium is formed between vascular bundles by dedifferentiation of parenchyma present in the medullary rays is called Interfascicular cambium. Both intra and interfascicular cambia join together and form into a ring of cambium called vascular cambium.

So, the correct option is ‘Medullary rays’.
