ASEXUAL REPRODUCTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
True, False, or Unknown:Bacteria typically reproduces sexually
A
True
B
False
C
Unknown
Explanation: 

Detailed explanation-1: -So, the above statement is false. The correct statement is Bacteria and yeast reproduce by asexual reproduction.

Detailed explanation-2: -So, bacteria can’t reproduce sexually, but they can exchange genetic information with each other. Using a pilus, two bacteria make contact with each other and exchange genetic material. This is called conjugation. Some bacteria simply take up DNA which is floating around in their environment.

Detailed explanation-3: -Though bacteria are predominantly asexual, the genetic information in their genomes can be expanded and modified through mechanisms that introduce DNA from outside sources. Bacterial sex differs from that of eukaryotes in that it is unidirectional and does not involve gamete fusion or reproduction.

Detailed explanation-4: -The given statement is True. Asexual reproduction is one of the reproductive process of passing genetic material from one generation to the next generation. The resulting offspring will have the same characters as the parent.

Detailed explanation-5: -Animals that reproduce asexually include planarians, many annelid worms including polychaetes and some oligochaetes, turbellarians and sea stars. Many fungi and plants reproduce asexually. Some plants have specialized structures for reproduction via fragmentation, such as gemmae in liverworts.
