As compared to a dicot root, a monocot root has
1 Inconspicuous annual rings
2 Relatively thicker periderm
3 More abundant secondary xylem
4 Many xylem bundles
Explanation:
Exp:D In dicot roots, the vascular structure are located in the middle of the roots, the arrangment of xylem and phloem is different in dicots, that it is in monocots the xylem is all located in the middle of dicot root and bundles of phloem are arranged around it by vascular combium. - In center of monocot root consist of xylem and phloem (vascular strand) and it surrounded by the cortex. Vascular strand is in the form of several alternate and radial xylem and phloem bundles. Monocot Root vs Dicot Root

Passage cells are found in
1 Dicot stem
2 Monocot root
3 Aerial root
4 Monocot stem.
Explanation:
Exp:B Passage cells are endodermal cells of older roots which have retained thin walls and casparian strips rather than becoming suberized and waterproof like the other cells around them, to continue to allow some symplastic flow to the inside. Passage cells function to allow transfer of solutes, such as calcium and magnesium into the steel, in order to eventually reach the transpiration system.

Casparian strips are characteristic of :
1 endodermis
2 epidermis
3 epiblema
4 xylem vessels
Explanation:
Exp:A The inner most layer of the cortex, called endodermis. It comprises a single layer of barrel shaped cells without any intercellular spaces. The tangential as well as radial wall of the endodermal cell have a deposition of water impermeable waxy material suberin in the form of casparian strips. Directions: In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:

The vascular bundles of dicot roots are
1 endarch and polyarch
2 exarch and polyarch
3 exarch and radial
4 endarch and collateral
Explanation:
Exp:C When xylem and phloem lie an different radaie xylem alternate phloem as roots. When protoxylem lies towards periphery and metaxylem towards the centre condition is called exarch as root.

When secondary growth in thickness is initiated in a dicot root
1 pericycle starels outside the primary xylem divide
2 anticlinal initials between xylem and phloem divide
3 cambial initials between xylem and phloem divide
4 parenchyma cells between xylem and phloem become meristematic
Explanation:
Exp:D Most of the dicotyledonous roots show secondary in thickness similar to that of dicotyledonous stem. However the monocotyledonous roots do not show any secondary growth. They remain entirely primary throughout their life the secondary tissue developed in the dicotyledonous roots are fundament ally quite similar to that of dicotyledonous stem. But the process initiates in some different manner. - The dicotyledonous roots posses a limited number of radial vascular bundles with exarch xylem normally the pith is very little or altogether absent.
