Question

Describe the process of conjugation in paramecium

Answer 1

Conjugation process: The two Paramecium of opposite mating types come in contact by their ventral surface during swimming. They stick together through their oral groove region. Following this attachment their cilia, Trichocysts, feeding apparatus degenerate.

Answer 2

Answer:

In conjugation, genetic material is transferred between two complimentary paramecia (syngen). Asexual reproduction must occur 50 times before conjugation can occur.

Explanation:

• In conjugation, genetic material is transferred between two complimentary paramecia (syngen). Asexual reproduction must occur 50 times before conjugation can occur.
• The conjugation bridge is created during the conjugation process, and the connected paramecia are referred to as conjugants.
• Both cells' macroscopic nuclei vanish. Each conjugate's micronucleus undergoes meiosis to produce four haploid nuclei. All three of the nuclei decay.
• Following this, the haploid micronuclei of each conjugant combine to produce diploid micronuclei, and cross-fertilization occurs.
• To generate exconjugants, the conjugants split apart. They are the same as the prior cells but distinct from them. Each exconjugate divides once again to produce 4 daughters Paramecia. New macronuclei are created by micronuclei.
