Directions: In the following questions, a statement of assertion (A) ...
Double fertilization is a characteristic feature of flowering plants. In this process, out of the two sperm nuclei, one sperm nucleus fuses with the egg nucleus to form an embryo (process is called syngamy) and another fuses with the secondary nucleus to form an endosperm (process is called triple fusion). Because two kinds of fusion— syngamy and triple fusion—take place, the process is known as double fertilisation.

Answer:
Assertion (A): Double fertilisation is unique to angiosperms.
Reason (R): Triple fusion occurs in asexual reproduction.
The correct answer is option 'C', which means that assertion (A) is true but reason (R) is false.
Explanation:
To understand this answer, let's first define the terms involved.
Double fertilisation: It is a unique process that occurs in angiosperms (flowering plants), where two fertilization events take place. In this process, one sperm fertilizes the egg to form the zygote, and the other sperm fuses with the two polar nuclei to form the endosperm, a nutritive tissue.
Triple fusion: This process is also specific to angiosperms and occurs during double fertilisation. In triple fusion, one sperm fuses with the two polar nuclei in the central cell of the embryo sac to form the endosperm.
Now, let's analyze the statements:
Assertion (A): Double fertilisation is unique to angiosperms.
This statement is true. Double fertilisation is a unique characteristic of angiosperms and is not observed in any other plant group. It plays a crucial role in the development of endosperm, which provides nourishment to the developing embryo.
Reason (R): Triple fusion occurs in asexual reproduction.
This statement is false. Triple fusion does not occur in asexual reproduction. Asexual reproduction involves the production of offspring without the involvement of gametes or fertilization. It includes various methods like fragmentation, budding, spore formation, etc. In asexual reproduction, the genetic material is not exchanged, and there is no fusion of gametes or nuclei.
Therefore, although both the assertion and reason are true, reason (R) does not provide the correct explanation for assertion (A). The reason presents a false statement about triple fusion occurring in asexual reproduction, which is not true.
Hence, the correct answer is option 'C', where assertion (A) is true but reason (R) is false.
Assertion (A): Double fertilisation is unique to angiosperms.
Reason (R): Triple fusion occurs in asexual reproduction.
The correct answer is option 'C', which means that assertion (A) is true but reason (R) is false.
