All (A)____ organisms are grouped under kingdom monera and unicellular eukaryotes are placed in kingdom (B)_____

Answer

To solve the question, we need to fill in the blanks regarding the classification of organisms in the context of the five kingdom system proposed by Whittaker.

### Step-by-Step Solution:

1. **Understanding Kingdom Monera**:
- Kingdom Monera includes all prokaryotic organisms. Prokaryotes are characterized by the absence of a true nucleus and membrane-bound organelles. They are unicellular and include bacteria and archaea.

2. **Identifying the First Blank (A)**:
- Since the question states "All (A)____ organisms are grouped under kingdom Monera," we can conclude that the correct term to fill in the blank is "prokaryotic."
- Therefore, the first blank (A) is filled with "prokaryotic."

3. **Understanding Unicellular Eukaryotes**:
- Unicellular eukaryotes are organisms that have a true nucleus and membrane-bound organelles, and they are primarily grouped under the kingdom Protista. This kingdom includes various unicellular organisms like protozoa and some algae.

4. **Identifying the Second Blank (B)**:
- The question states "unicellular eukaryotes are placed in kingdom (B)_____." Based on our understanding, the correct term to fill in this blank is "Protista."
- Therefore, the second blank (B) is filled with "Protista."

### Final Answers:
- (A) Prokaryotic
- (B) Protista
