Which of the following bracketed keys correctly describes the Whittaker's five kingdom classification ?

Options

A.
B.
C.
D.

Answer

To solve the question regarding Whittaker's five kingdom classification, we will break down the classification into its components and analyze each kingdom according to the characteristics described.

### Step-by-Step Solution:

1. **Understanding the Five Kingdoms**:
- Whittaker's classification divides living organisms into five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia.

2. **Identifying Characteristics of Each Kingdom**:
- **Monera**: This kingdom includes all prokaryotic organisms, which are unicellular and lack a true nucleus. Examples include bacteria.
- **Protista**: This kingdom consists of eukaryotic organisms, primarily unicellular, that do not fit into the other kingdoms. Examples include protozoa and some algae.
- **Fungi**: This kingdom includes multicellular and unicellular organisms that are heterotrophic (saprophytic) and have cell walls made of chitin. Examples include molds and mushrooms.
- **Plantae**: This kingdom consists of multicellular, autotrophic organisms that perform photosynthesis and have cell walls made of cellulose. Examples include flowering plants and ferns.
- **Animalia**: This kingdom includes multicellular, heterotrophic organisms that do not have cell walls and obtain food by ingestion (holozoic). Examples include mammals, birds, and insects.

3. **Analyzing the Options**:
- The question asks which option correctly describes the Whittaker's five kingdom classification. Each option will need to be evaluated based on the characteristics outlined above.

4. **Correct Option**:
- After analyzing the characteristics of each kingdom, the correct option that accurately represents the classification is option C. This option correctly identifies:
- Monera as unicellular and prokaryotic.
- Protista as unicellular and eukaryotic.
- Fungi as multicellular and heterotrophic.
- Plantae as multicellular and autotrophic.
- Animalia as multicellular and heterotrophic.

### Conclusion:
The correct answer to the question is **option C**, as it accurately describes the Whittaker's five kingdom classification.
