Which of the following kingdoms contains primarily multicellular, larger-celled, photosynthetic organisms?

Options

A. Animalia
B. Plantae
C. Archaea
D. Fungi

Explanation

To solve the question "Which of the following kingdoms contains primarily multicellular, larger-celled, photosynthetic organisms?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question is asking for a kingdom that is primarily made up of multicellular organisms that are capable of photosynthesis.

2. **Identify the Options**: The options provided are:
- A) Animalia
- B) Plantae
- C) Archaea
- D) Fungi

3. **Analyze Each Option**:
- **Option A: Animalia**: This kingdom includes multicellular organisms, but they are not photosynthetic. Animals obtain their energy by consuming other organisms.
- **Option B: Plantae**: This kingdom includes primarily multicellular organisms that are photosynthetic. They contain chlorophyll, which allows them to perform photosynthesis.
- **Option C: Archaea**: This kingdom consists of unicellular organisms, primarily prokaryotes, and they do not perform photosynthesis.
- **Option D: Fungi**: This kingdom includes multicellular organisms, but they are not photosynthetic. Fungi obtain nutrients through absorption and are saprophytic.

4. **Determine the Correct Answer**: Based on the analysis:
- Option A is incorrect because animals are not photosynthetic.
- Option B is correct because plants are multicellular, larger-celled, and photosynthetic.
- Option C is incorrect because Archaea are unicellular and not photosynthetic.
- Option D is incorrect because fungi are not photosynthetic.

5. **Conclusion**: The kingdom that contains primarily multicellular, larger-celled, photosynthetic organisms is **Option B: Plantae**.

### Final Answer:
**B) Plantae**
