Question

11) Ciliates generally have a micronculeus and a macronucleus. During conjugation the micronuclei are exchangea between two compatible mates (haploid) resulting in diploid micronuclei. How is this similar to bacterial conjugation? A) physical touching occurs B) it is sexual, allowing recombination of genes C) it is not a form of reproduction, no new cells arise D) all of the above are shared characteristics of bacterial and ciliate conjugation 12) Protista is the most diverse of all the kingdoms containing single celled and multi-celled organisms, some with multiple nuclel, unique organelles, odd cell walls, funky cell division, sexual recombination, mitosis, fission and asexual reproduction. Some have parasitic, symbiotic, autotrophic and/or mixotrophic lifestyles. Why in the world are all these organisms grouped together? A) all are unicellular and motile B) rRNA genes are homologous C) all are microscopic D) Its a trash can, any organisms that don't fit elsewhere land in this kingdom

Answer 1

11. C

No new organism or cell is formed in both ciliated and bacterial conjugation. But both in this cases the transfer of genetic material takes place.

12. A

Every organisms in Kingdom Protista are single-celled i.e., unicellular and motile. Cilia or flagella helps the organisms in this Kingdom to move.
