II:	Plant cells are enclosed by a relatively inextensible cell wall.

Of the two statements:

1. Both I and II are correct and II explains I
2. Both I and II are correct but II does not explain I
3. I is correct but II is incorrect
4. I is incorrect but II is correct

Cells at the end of prophase of mitosis, when viewed under the microscope, do not show:

  
1. Only I and II are correct
2. Only III and IV are correct
3. Only II, III and IV are correct
4. I, II, III and IV are correct

The stage of mitosis at which morphology of chromosomes is most easily studied is the:
1. Prophase
2. Metaphase
3. Anaphase
4. Telophase

Consider the following events:
I. Centromere split and chromatids separate
II. Chromatids move to opposite poles
The stage of mitosis characterized by these two events is:
