Show Solution
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Biological classification places organisms into five kingdoms based on cell structure, mode of nutrition, and reproduction.
Detailed Explanation:
- (1) Correct. Cyanobacteria (Blue-green algae) are prokaryotic autotrophs (photosynthetic) and belong to Kingdom Monera.
- (2) Incorrect. While most bacteria are heterotrophs, many are autotrophic (chemosynthetic or photosynthetic).
- (3) Incorrect. Slime moulds are saprophytic but they are classified under Kingdom Protista.
- (4) Incorrect. Mycoplasma are unique because they lack a cell wall.
Step 2: Final Answer:
Statement (1) is correct.
