Question

The most common mode of reproduction in bacteria is
A. Fission
B. Budding
C. Sexual reproduction
D. Sporulation

Answer 1

Hint: It is a type of asexual reproduction where the parent cell divides into two halves and each half grows into an adult. This type of division is mostly seen in single celled organisms.

Complete Answer:
Reproduction allows for the species' continuity, down the generations. It consists of two types: asexual and sexual reproduction, based on whether one or two individuals are involved in the reproductive process.

A) Among single-celled species, and in plants and animals with relatively simple organisations, asexual reproduction is common. Binary fission is a form of asexual reproduction used by members of the archaea and bacteria. It results in cell division of the parent cell to create two viable cells that can replicate the process.

B) Budding is a type of asexual reproduction in which small buds are formed in the parent cell that gradually split and mature into new species. This type of reproduction is seen in yeast.

C) Sexual reproduction involves the formation and fusion of gametes. In contrast to asexual reproduction, it is a complicated and slower process. Many of the higher animals reproduce by sexual method almost entirely.

D) The members of Kingdom Fungi and simple organisms like algae reproduce through special asexual reproductive structures. These structures are typically microscopic motile structures called zoospores.

Thus, the correct answer is fission.

Note: Asexual reproduction does not involve the fusion of gametes. It is common in species such as mushrooms, algae and some invertebrate animals that have a relatively basic organisation. The offspring produced by asexual method are identical and are known as clones.
