Ciliophora mode of reproduction
Ciliates contain two types of nuclei: somatic "macronucleus" and the germline "micronucleus". Only the DNA in the micronucleus is passed on during sexual reproduction (conjugation). On the other hand, only the DNA in the macronucleus is actively expressed and results in the phenotype of the organism. Macronuclear DNA is derived from micronuclear DNA by amazingl… WebThe macronucleus has multiple copies of a ciliates genome and controls RNA synthesis for cellular regulation. The diploid micronuclei undergo meiosis and are exchanged during …

WebAsexual reproduction in free-living species usually involves nuclear division and the division of the cell into two identical daughter cells of equal size by binary fission. In parasitic protozoans and some free-living species, multiple fission, resulting in the production of many offspring that may not resemble the parent cell, is normal. During the cycle of growth and … WebAlso two other excystation modes were observed. During the rare mode, the excystation vacuole breaks the thin membrane instead of the cyst wall that ruptures under the pressure of the body of the regenerating specimen. During the reproduction mode, the regenerating specimen divides within the resting cyst, producing two to four tomites.
WebThe mode of reproduction in protozoa is variable among different groups, however it is basically a cell division. In protozoa, reproduction takes place by asexual (involving mitosis) and sexual (involving meiosis); however, some reproduce asexually only. ...
