Which structures perform the function of mitochondria in bacteria?
1 Nucleoid
2 Ribosomes
3 Cell wall
4 Mesosomes
Explanation:
Mesosomes are found in the membranes of bacterial cells. These are organelles formed by plasma membrane infoldings. It increases the surface area of the plasma membrane to carry out various enzymatic activities and also helps in secretion process as well as in bacterial respiration.

In Angiosperm all the four microspores of tetrad are covered by a layer which is formed by : -
1 Pectocellulose
2 Callose
3 Cellulose
4 Sporopollenin
Explanation:
The callose plays an important role in different stages of development of plants. It is a plant polysaccharide which is produced to act as a temporary cell wall in response to stimuli such as stress or damage.

Transduction in bacteria is mediated by:
1 plasmid vectors
2 phage vectors
3 cosmids
4 F-factors
Explanation:
Transduction is the process by which a virus transfers genetic material from one bacterium to another. - Bacteriophage mediate horizontal gene transfer through a mechanism known as transduction, therefore, transduction in bacteria is mediated by phage vector.

Organisms, which fix atmospheric nitrogen in the soil, fall under the category of:
1 bacteria
2 green algae
3 soil fungi
4 mosses
Explanation:
Microscopic single- celled organisms lacking a distinct nucleus are known as bacteria. - Organisms which fix atmospheric nitrogen in the soil are come under bacteria because they are only prokaryotic organism who have certain enzymes.
