BIOXI15: PLANT GROWTH AND DEVELOPMENT
337975
We may say that even differentiation in plants is ____A____, because cells/tissues arising out of the same meristem have____B____ structures at maturity
1 A - open, B - same
2 A - open, B - different
3 A - close, B - same
4 A - close, B - different
Explanation:
We may say that even differentiation in plants is open, because cells/tissues arising out of the same meristem have different structures at maturity.

During differentiation, cells undergo few to major structural changes in which of the following organelles?
1 Cell walls
2 Protoplasm
3 Both 1 and 2
4 None of the above
Explanation:
During differentiation, cells undergo few to major structural changes in organelles like cell walls and protoplasm.

Formation of meristems - interfascicular cambium and cork cambium from fully differentiated parenchyma cells is the example of which phenomenon?
1 Dedifferentiation
2 Re-differentiation
3 Differentiation
4 None of the above
Explanation:
The living differentiated cells, that by now have lost the capacity to divide can regain the capacity of division under certain conditions. This phenomenon is termed as dedifferentiation. For example, formation of meristems - interfascicular cambium and cork cambium from fully differentiated parenchyma cells.

Read the following statements and select the incorrect statement.
1 Cells positioned away from root apical meristems differentiate as root-cap cells
2 The final structure at maturity of a cell/ tissue is also determined by the location of the cell within.
3 Cells those pushed to the periphery from root apical meristems mature as pith cells
4 All are correct.
Explanation:
Cells positioned away from root apical meristems differentiate as root-cap cells, while those pushed to the periphery mature as epidermis.
