19. Analysis through cell division and its types

7.5 m.

In the given exercise, an Assertion is followed by the corresponding Reason. Mark the suitable answer from the given options:

1.

Assertion:	Interphase occupies more than \(95\) % of total generation time in cell division.
Reason:	In this phase, the cell prepares for the next division by synthesising essential substances required for cellular growth and replicating genetic material.

Both assertion and reason are correct and reason is the correct explanation of assertion.
Both assertion and reason are correct, but reason is not the correct explanation of assertion.
Assertion is correct but reason is false.
Assertion is false, but reason is correct.

2.

Assertion:	In meiosis -I, the germ cells divide into two daughter cells with only half the number of chromosomes compared to mother germ cells.
Reason:	Meiosis cell division is an equatorial cell division.

Both assertion and reason are correct and reason is the correct explanation of assertion.
Both assertion and reason are correct, but reason is not the correct explanation of assertion.
Assertion is correct but reason is false.
Assertion is false, but reason is correct.

3.

Assertion:	Metaphase plate is made up of spindle fibres.
Reason:	All of the chromosomes become aligned at the equatorial plane and form the metaphase plate.

Both assertion and reason are correct and reason is the correct explanation of assertion.
Both assertion and reason are correct, but reason is not the correct explanation of assertion.
Assertion is correct but reason is false.
Assertion is false, but reason is correct.
