Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): A typical angiosperm embryo sac at maturity is 8 -nucleate but 7 -celled. Reason (R): The two polar nuclei are situated below the egg apparatus and are surrounded by individual cell walls to form two separate cells. In the light of the above statements, choose the most appropriate answer from the o

Step-by-step solution

Assertion (A) is true because a typical angiosperm embryo sac (Polygonum type) has 8 nuclei but only 7 cells at maturity. Reason (R) is false because out of the eight nuclei, only six are surrounded by cell walls and organised into cells (three in the egg apparatus and three antipodals). The remaining two nuclei, called polar nuclei, are not surrounded by individual cell walls; instead, they share the cytoplasm of the large central cell situated below the egg apparatus. Therefore, the Assertion is true but the Reas
