Formation of which tissue is example of dedifferentiation
1 Cork cambium
2 Apical meristem
3 Intrafascicular cambium
4 Root apical merisatem
Explanation:
Differentiation is the ability of the cells to get specialised. Dedifferentiation is the ability of the cells which can regain its capacity for cell division under certain conditions. Formation of interfascicular cambium and cork cambium from fully differentiated parenchyma cells is an example of dedifferentiation.

Choose the odd one out with respect to components of bark
1 Phellogen
2 Pith
3 Secondary xylem
4 2 and 3
Explanation:
Secondary xylem and pith is not the part of bark. Bark is a non-technical term that refers to all the tissues exterior to the vascular cambium. Consisting of periderm (i.e. phellem, phellogen and phelloderm) and secondary phloem.

Assertion : The lenticel is meant for gaseous exchange Reason : Lenticel checks excessive evaporation of water.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
Assertion is true but Reason is false. Lenticels permit the exchange of gases between the outer atmosphere and the internal tissue of the stem.

The cork cambium, cork and secondary cortex are collectively called
1 Phellogen
2 periderm
3 Phellem
4 phelloderm
Explanation:
The periderm is a secondary protective structure and is made up of cork cambium (phellogen), cork (phellem) and secondary cortex(phelloderm)

Formation of which tissue is example of dedifferentiation
1 Cork cambium
2 Apical meristem
3 Intrafascicular cambium
4 Root apical merisatem
Explanation:
Differentiation is the ability of the cells to get specialised. Dedifferentiation is the ability of the cells which can regain its capacity for cell division under certain conditions. Formation of interfascicular cambium and cork cambium from fully differentiated parenchyma cells is an example of dedifferentiation.
