Multicellular organism with holophytic nutrition belong to how many kingdoms in Whittaker system?

Options

A. One
B. Two
C. Three
D. Five

Answer

To determine how many kingdoms in the Whittaker system contain multicellular organisms with holophytic nutrition, we can follow these steps:

### Step 1: Understand Holophytic Nutrition
Holophytic nutrition refers to the ability of an organism to synthesize its own food through photosynthesis. This means that these organisms can convert light energy into chemical energy, typically using chlorophyll.

**Hint:** Remember that holophytic nutrition is primarily associated with organisms that can perform photosynthesis.

### Step 2: Identify the Relevant Kingdoms
In the Whittaker system of classification, there are five kingdoms:
1. Monera
2. Protista
3. Fungi
4. Plantae
5. Animalia

**Hint:** Focus on the characteristics of each kingdom to identify which ones include multicellular organisms that can perform photosynthesis.

### Step 3: Analyze Each Kingdom
- **Monera:** This kingdom includes unicellular organisms like bacteria, which do not have holophytic nutrition.
- **Protista:** This kingdom contains both unicellular and some multicellular organisms (like certain algae) that can perform photosynthesis, but it primarily includes unicellular organisms.
- **Fungi:** This kingdom consists of multicellular organisms that do not perform photosynthesis; they are heterotrophic.
- **Plantae:** This kingdom includes multicellular organisms (plants) that perform photosynthesis and have holophytic nutrition.
- **Animalia:** This kingdom consists of multicellular organisms that are heterotrophic and do not perform photosynthesis.

**Hint:** Focus on the Plantae kingdom, as it is known for organisms that can perform photosynthesis.

### Step 4: Conclusion
From the analysis, we can conclude that multicellular organisms with holophytic nutrition belong exclusively to the Plantae kingdom in the Whittaker system.

**Final Answer:** Multicellular organisms with holophytic nutrition belong to **one kingdom** in the Whittaker system, which is the **Plantae** kingdom.
