Multicellular producers belong to kingdom

Options

A. Protista
B. Protista and Plantae
C. Plantae
D. Plantae and Mycota

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the kingdom to which multicellular producers belong, according to the Whittaker classification system.

2. **Whittaker's Classification**: In 1969, Robert H. Whittaker proposed a classification system that divided living organisms into five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia. This classification was based on three criteria: complexity of cell structure, complexity of the organism's body, and mode of nutrition.

3. **Identifying Multicellular Producers**:
- Producers are organisms that can make their own food through photosynthesis.
- Multicellular producers are typically green plants that have complex structures and are capable of photosynthesis.

4. **Analyzing the Options**:
- **Option 1: Protista** - This kingdom primarily consists of unicellular organisms. While some protists can perform photosynthesis (like algae), they are generally unicellular, so this option is incorrect for multicellular producers.
- **Option 2: Protista and Plantae** - This option is misleading because, as stated, Protista includes unicellular producers, while Plantae includes multicellular producers. Therefore, this option is also incorrect.
- **Option 3: Plantae** - This kingdom includes all green plants, which are multicellular and capable of photosynthesis. Thus, this option is correct.
- **Option 4: Mycota** - This term refers to fungi and is not recognized as a kingdom in Whittaker's classification, making this option incorrect.

5. **Conclusion**: Based on the analysis, the correct answer is that multicellular producers belong to the kingdom **Plantae**.
