Question

Bacteria resembles
A) Nostoc species
B) Mitochondria
C) Chlamydomonas
D) None of the above

Answer 1

Hint:-Bacteria are a sort of natural cell. They comprise a large area of prokaryotic microorganisms. Characteristically a few micrometers in length, bacteria have a figure of shapes, ranging from spheres to rods and spirals. Bacteria were among the most important life forms to emerge on Earth, and are present in most of its habitats.

Complete step-by-step solution:-
Nostoc is a miscellaneous genus of cyanobacteria. Bacteria look like Nostoc. Like bacteria, they do not
have a well distinct nucleus. They develop by fission like bacteria. However, Nostoc is not bacteria. They
are competent in fixing atmospheric nitrogen and therefore are compassionate to plants.
Mitochondria are covering-bound cell organelles (mitochondrion, singular) that make most of the
chemical energy required to control the cell’s biochemical reactions. Chemical energy formed by the mitochondria is stored up in a minute molecule known as adenosine triphosphate (ATP). Found in immobile water and on moist soil, in freshwater, seawater, and also in snow as “snow algae” Chlamydomonas is a genus of green algae consisting of about 325 species all unicellular flagellates.
Thus, the accurate answer is “Nostoc species”.

Note:- Nostoc can be found in soil, on damp rocks, at the base of lakes and springs, and not often in marine habitats. It may also cultivate symbiotically surrounded by the tissues of plants, like the evolutionarily most primitive angiosperm Gunnera and the hornworts (a cluster of bryophytes), providing nitrogen to its host through the deed of terminally differentiated cells known as heterocysts. These bacteria have photosynthetic pigments in their cytoplasm to carry out photosynthesis.
