Why do some scientists call conjugation sexual reproduction and other do not? Some do because there is a presence of two organisms, some don’t because there is not actual reproduction just transfer of DNA. … What organisms have cilia, flagella and/or pseudopods?
Is conjugation considered sexual reproduction?
Conjugation is a form of sexual reproduction in bacteria. Two individual cells are united by a tube formed by outgrowths from one or both cells. Genetic material from one cell (designated the male) then passes through the tube to unite with genetic material in the other cell (designated female).18-Sep-2017

What is meant by conjugation in biology?
Conjugation, in biology, sexual process in which two lower organisms of the same species, such as bacteria, protozoans, and some algae and fungi, exchange nuclear material during a temporary union (e.g., ciliated protozoans), completely transfer one organism’s contents to the other organism (bacteria and some algae),
Why is it wrong to say sexual reproduction occurs in bacteria?
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.

What do you mean by vegetative reproduction?
Vegetative reproduction, any form of asexual reproduction occurring in plants in which a new plant grows from a fragment of the parent plant or grows from a specialized reproductive structure (such as a stolon, rhizome, tuber, corm, or bulb).

In English, we can break the tenses down to five main areas: past, present, future, perfect and conditional. Past tense conjugations: Simple past: Zoe went to the store. Past progressive: Zoe was going to the store.
What is one interesting fact about the paramecium?
Paramecia are from the protozoa class. Paramecia have no eyes, no heart, no brain, and no ears. Paramecia are able to undergo reproduction and digestion even without many of the systems in other organisms. When a paramecium ingests food it also ingests water, which is pumped out via the vacuole pumps.

What is an advantage of sexual reproduction?
The advantages of sexual reproduction: produces genetic variation in the offspring. the species can adapt to new environments due to variation, which gives them a survival advantage. a disease is less likely to affect all the individuals in a population.
Why is sexual reproduction important?
Sexual Reproduction produces variable offspring creating diversity and variation among populations. It is important for plants as it provides variation to the progeny that helps in better survival and helps it to gain its own uniqueness within the species and remove the unwanted genes.
Why is reproduction so important?
Reproduction is important for the survival of all living things. Without a mechanism for reproduction, life would come to an end. Asexual reproduction refers to simple cell division that produces an exact duplicate of an organism.
What are 3 advantages of asexual reproduction?

What are the advantages and disadvantages of asexual and sexual reproduction?
Asexual Reproduction Sexual Reproduction
Advantages Time Efficient; no need to search for mate, requires less energy Variation, Unique., organism is more protected
Disadvantages No variation – if the parent has a genetic disease, offspring does too. Requires two organisms, requires more energy

What is vegetative reproduction give examples?
Vegetative propagation is a type of asexual reproduction that produces progeny by any vegetative propagule (rhizome, tubers, suckers etc.) without gamete formation and fertilization of male and female gametes. For example, Tuber of potato, the rhizome of ginger.

Flowers produced are of superior quality.
Desirable character of fruit can be maintained.
