Question

Hologamy in most of Sarcodina members is for
A) Asexual reproduction
B) Fragmentation
C) To avoid the unfavorable condition
D) None of the above

Answer 1

Hint: Sarcodina is a taxonomic group of protozoa. It is the largest phylum of protozoans. It comprises the amoebas and related organisms. They are a single-celled organism that engulfs their food and moves with the help of pseudopodia.

Complete Answer:
- Hologamy is a type of sexual reproduction, Hologamy is seen in very lower algae which are very uncommon.So option A can not be the correct answer.
- Fragmentation is a type of asexual reproduction, so option B is also not a correct answer. Hologamy has nothing to do with unfavorable conditions. It is the nature of a specific organism.

So, ‘none of the above’ is the correct answer.

Additional information: Hologamy is a sexual mode of reproduction that involves the fusion of two similar organisms. In hologamy, two organisms act as two gametes. Hologamy also involves genetic recombination that further leads to the variations. Variation is a major source of evolution. While in syngamy, the organism reproduces by the fusion of two gametes.

Note: The mode of reproduction in members of Sarcodina is syngamy. Syngamy is the fusion of two gametes. The members of Sarcodina also reproduce by asexual means such as budding. Hologamy is a mode of reproduction but not in Sarcodina. You can see Hologamy in some green algae. They are alike and haploid in nature.
