Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R). Assertion (A): Cleavage polyembryony is found in Citrus Reason (R): In Cleavage polyembryony, the zygote divides to form several embryos. In light of the above statements, choose the correct answer from the options given below.

Options

  1. ABoth (A) and (R) are true and (R) is the correct explanation of (A).
  2. BBoth (A) and (R) are true but (R) is NOT the correct explanation of (A).
  3. C(A) is true but (R) is false.
  4. D(A) is false but (R) is true.

Correct answer

D. (A) is false but (R) is true.

Step-by-step solution

Assertion (A) is false because polyembryony in Citrus is adventive (nucellar) polyembryony. In this process, some of the nucellar cells surrounding the embryo sac start dividing, protrude into the embryo sac, and develop into embryos. Reason (R) is true because cleavage polyembryony is the phenomenon where a single zygote or proembryo splits or cleaves to form multiple embryos (commonly seen in gymnosperms like Pinus ). Therefore, (A) is false but (R) is true. Answer: (A) is false but (R) is true.
