A
suberized exodermis, polyarch xylem , pith
B
exodermis, endarch, tetarch closed bundles
C
conjoint, collateral, open, polyarch vascular bundle
D
suberized exodermis, casparian strip, passage cells, cambium
Answer
suberized exodermis, polyarch xylem , pith
Explanation
Solution
In the cortex of monocot root, we observe a few layers of cell below the epidermis which have thick walls due to the deposition of a chemical suberin. These layers of suberized cells are called exodermis. There are also number alternating zones of xylem present in root. The number of xylem patches far exceeds to ten. That is why, they are called polyarch. In monocot root, there is a large sized pith made up of parenchyma tissues.
