Which of the following is a major branch of the domain bacteria?
a. eubacteria
b. cyanobacteria
c. both of the above
d. none of the above

Answer : The correct answer is -

a. Eubacteria.

Bacteria constitute the simplest forms of life on earth.

Eubacteria is a major branch of bacteria, which includes organisms that are devoid of true nucleus and membrane bound subcellular compartments (cell organelles). Their genetic material is present within the cytoplasm of the cell.

Cyanobacteria (also termed blue green algae) are the photosynthetic bacteria that come under eubacteria.

Thus, option a) Eubacteria is the right answer.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.
