Question

The type of syngamy seen in trichonympha is
a. Hologamy
b. Anisogamy
c. Isogamy
d. Conjugation

Answer 1

The process of the fusion of the female-male gametes in order to give rise to a new separate organism or progenies and inductee its advance is called Fertilisation or fertilization. The process of the fusion of the sperm cell with the two glacial nuclei in the duration of the double fertilization is acknowledged as triple fusion.

Complete answer:
We can say that the generative fertilization, insemination, pollination, fecundation, syngamy, and impregnation are the other names of Fertilisation or fertilization.
As we know already, the amphimixis is the process of fusion between the haploid male nucleus and the egg nucleus. It is also known as syngamy.

This process normally leads to the formation of a diploid zygote. The form of sexual reproduction in which the sex cells are of the same size and construction as the somatic cells.
Trichonympha lives in the intestine termite types and aids them to disrupt the cellulose which they yield from the wood. They produce the haploid gametes which are similar to the organisms which are known as zooflagellates. So, this process is classified as Hologamy.

Option B:
The process of sexual imitation formation that comprises the combination or fusion of two gametes, which normally differ in size and form is called anisogamy.

Option C and D:
The process of Isogamy is the formation of sexual reproduction which involves gametes of comparable morphology. However, the provisional unification of two bacteria or unicellular creatures for the exchange of genetic material is called conjugation.

Hence, the correct answer is option (A).

Note: Trichonympha is from the genus of parabasalid protists. They live in the intestine of many termite species. We can say that they are examples of the symbiotes as they break down roughage in the wood and plant fibers which their hosts eat. Thus, we can say that these are no good for the host in which they live. They will harm the host rapidly and conquer it. This makes them parasites.
