reproduction of bacteria organisms dna

It is the most common mode of asexual reproduction. The cytoplasm and nucleoid of a bacterial cell divide equally into two, following replication of DNA. The cell wall and cytoplasm also split resulting in the formation of two daughter cell..

show a primitive type of sexual reproduction called genetic recombination. Conjugating Bacteria In this process, the exchange of genetic materials takes place by a process called conjugation . Conjugating bacterial cells are in contact through a hollow tube called pilus. ..

One of the unsolved mysteries in biology is that of viruses. Due to the absence of a cellular organization viruses cannot be placed with either prokaryotes or eukaryotes. They are considered as intermediate between living and non-living systems. Viruses are active and show reproducti..

Bacteria are minute microscopic prokaryotes. They are unicellular organisms, which are usually identified by their specific activities, more than their general organisati..

Flowers are primarily concerned with sexual reproduction. But, in some plants such as Agave, the flower bud becomes modified into specialised structures called the bulbils . The bulbils are fleshy on account of storage of food in the floral leaves. The bulbils drop from the parent plant o..

. According to this theory, Each adult organism grows from a zygote. The zygote is a diploid cell having two sets of chromosomes - maternal and paternal. The zygote by mitotic divisions results in the formation of an adult and thus, all the vegetative or somatic cells of an organismh..

Sexual Reproduction - Sexual reproduction mostly occurs in higher multicellular plants and animals. However, it is also seen in lower organisms like the bacteria, Spirogyra (an alga) and Paramoecium (a protozoa..

These are bacteria which are unable to manufacture their own organic food and hence are dependent on external source. These bacteria can be distinguished into three groups as follows: Saprophytic Bacteria: These bacteria obtain their nutritional req..
