Given below are two statements : One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : A typical unfertilised, angiosperm embryo sac at maturity is 8 nucleate and 7-celled.
Reason (R) : The egg apparatus has 2 polar nuclei.
In the light of the above statements, chocse the correct answer from the options given below :
- A
A is false but R is true
- B
Both A and R are true and R is the correct explanation of A
- C
Both A and R are true but R is NOT the correct explanation of A
- D
A is true but R is false
Assertion: A mature angiosperm embryo sac has 7 cells and 8 nuclei — one egg, two synergids, three antipodals, and one central cell with two polar nuclei. So A is true.
Reason: The egg apparatus consists of one egg cell and two synergids only; the two polar nuclei lie in the central cell, not in the egg apparatus. So R is false.
A is true but R is false.
