Which of the following is a correct statement?

  1. Cyanobacteria are a group of autotrophic organisms classified under Kingdom Monera.
  2. Bacteria are exclusively heterotrophic organisms.
  3. Slime moulds are saprophytic organisms classified under Kingdom Monera.
  4. Mycoplasma have DNA, ribosome and cell wall.

Answer

(1) Cyanobacteria are a group of autotrophic organisms classified under Kingdom Monera.

Solution

As per NCERT, cyanobacteria (blue-green algae) have chlorophyll a similar to green plants and are photosynthetic autotrophs; they are eubacteria placed under Kingdom Monera — (1) is correct.

⇒ Bacteria are not exclusively heterotrophic: many are photosynthetic or chemosynthetic autotrophs — (2) is wrong.

⇒ Slime moulds are saprophytic protists, classified under Kingdom Protista — (3) is wrong.

⇒ Mycoplasma completely lack a cell wall — (4) is wrong.
