Pick the correct statements.

Options

A. Absence of tissue grade-Monera and protista
B. Absence of cell wall-Protista (few) and Animalia
C. Heterotrophic nutrition - Fungi and Animalia
D. All the above

Answer

To solve the question "Pick the correct statements," we will analyze each of the provided options based on the characteristics of the five kingdoms of life as classified by R.H. Whittaker.

### Step-by-Step Solution:

1. **Understanding the Five Kingdoms**:
- The five kingdoms according to Whittaker's classification are:
- Monera
- Protista
- Fungi
- Plantae
- Animalia

2. **Analyzing the First Statement: Absence of Tissue Grade**:
- The absence of tissue grade refers to organisms that do not have a tissue level of organization.
- Monera and Protista are unicellular organisms and do not possess a tissue grade.
- Therefore, this statement is **correct**.

3. **Analyzing the Second Statement: Absence of Cell Wall**:
- Monera has a cell wall made of amino acids and polysaccharides, not cellulose.
- Some Protista lack a cell wall, while others have it.
- Fungi have a cell wall made of chitin, Plantae have a cell wall made of cellulose, and Animalia do not have a cell wall.
- Thus, the statement about the absence of cell wall is **correct** for some Protista and Animalia.

4. **Analyzing the Third Statement: Heterotropic Nutrition**:
- Monera can be both autotrophic and heterotrophic.
- Protista can also be autotrophic or heterotrophic.
- Fungi are exclusively heterotrophic.
- Plantae are exclusively autotrophic.
- Animalia are exclusively heterotrophic.
- Therefore, the statement regarding heterotropic nutrition is **correct** as it applies to fungi and Animalia.

5. **Conclusion**:
- Since all three statements are correct, the answer is **"All of the above."**

### Final Answer:
All of the above statements are correct.
