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.

Directions: In the following questions, a statement of assertion (A) ...
Assertion : Double fertilisation is unique to angiosperms.
Reason : Triple fusion occurs in both fertilizations.
-The process of double fertilisation is a unique characteristic of angiosperms, which involves the fusion of two male gametes with two female gametes.
-Triple fusion, on the other hand, refers to the fusion of one male gamete with the two polar nuclei present in the embryo sac.
-Both double fertilisation and triple fusion occur in angiosperms, but they are separate and distinct processes.
Explanation:
Double fertilisation is a unique reproductive mechanism found only in angiosperms (flowering plants). It involves the fusion of two male gametes with two female gametes, resulting in the formation of two distinct structures - the zygote and the endosperm. The zygote develops into the embryo, while the endosperm provides nourishment to the developing embryo.
Triple fusion, on the other hand, occurs within the process of double fertilisation. It involves the fusion of one male gamete with the two polar nuclei present in the embryo sac. This fusion results in the formation of the triploid nucleus, which gives rise to the endosperm.
Both double fertilisation and triple fusion are unique to angiosperms and play crucial roles in their reproductive process. However, it is important to note that triple fusion is a part of double fertilisation and is not a separate process.
In conclusion, the statement of assertion is true as double fertilisation is indeed unique to angiosperms. The reason is false because although triple fusion occurs in both fertilisations, it is a part of double fertilisation and not a separate process. Therefore, option C is the correct answer.
Reason : Triple fusion occurs in both fertilizations.
-The process of double fertilisation is a unique characteristic of angiosperms, which involves the fusion of two male gametes with two female gametes.
-Triple fusion, on the other hand, refers to the fusion of one male gamete with the two polar nuclei present in the embryo sac.
-Both double fertilisation and triple fusion occur in angiosperms, but they are separate and distinct processes.

In conclusion, the statement of assertion is true as double fertilisation is indeed unique to angiosperms. The reason is false because although triple fusion occurs in both fertilisations, it is a part of double fertilisation and not a separate process. Therefore, option C is the correct answer.
