Anatomically fairly old dicotyledonous root is distinguished from the dicotyledonous stem by:
1 Position of protoxylem
2 absence of secondary xylem
3 Absence of secondary phloem
4 Presence of cortex
Explanation:
Exp:A Anatomically fairly old dicotyledonous root is distinguished from the dicotyledonous stem by position of cortex. Protoxylem is the first formed xylem developing from procambium and consisting of narrow cells with annular, spiral or scalariform wall thickenings. Thus, the position of protoxylem and metaxylem can help in distinguishing the fairly old dicotyledonous root from dicotyledonous stem very well.

Fibrous root system is mostly found in:
1 monocot plants
2 dicot plants
3 pteridophytes
4 bryophytes
Explanation:
Exp:A Fibrous root system is mostly found in monocot plant. The anatomy of the monocot root is similar to the dicot root. As compared to the dicot root which have xylem bundles, there are usually more than six (Polyarch) xylem bundles in the monocot root. Pith is large and well developed.

Epidermis is specialized for
1 respiration
2 absorption
3 protection
4 All of these
Explanation:
) : Epidermis is specialized for respiration, absorption and protection also. The plant epidermis is a protective tissue that covers the entire surface of the plant. It regulates the gas exchange in plant cells. The epidermis protects the plant from infection and water loss. It also protects against mechanical injury and parasitic fungus invasion. The epidermis is in charge of absorbing water and essential minerals.

Triradiate vascular bundles can be traced in
1 monocot roots
2 dicot root
3 monocots
4 dicot stem
Explanation:
Exp:B Dicot root contains radial vascular bundle. In the center, there is a tiny parenchymatous pith. It's also possible that dicot root don't have it. Vascular bundle are in the dicot roots 2-6 in number.
