Answer

To solve the question "Plants comprise not more than," we will analyze the options provided based on the information given in the video transcript.

### Step-by-Step Solution:

1. **Understanding Total Species**:
- The total number of species on Earth is approximately 1.5 million, which includes both plants and animals.

2. **Analyzing Species Distribution**:
- According to the IUCN 2004 report, more than 70% of the recorded species are animals. This indicates that a significant majority of species are not plants.

3. **Calculating Plant Species Percentage**:
- Since more than 70% of the species are animals, this implies that the remaining percentage, which accounts for plants, is less than or equal to 30%.
- The video states that not more than 22% of the species are plants.

4. **Identifying the Correct Option**:
- The options provided are:
- A) 20% of total species
- B) 22% of total species
- C) 32% of total species
- D) 30% of total species
- Since the video confirms that plants comprise not more than 22% of the total species, we can conclude that option B (22% of total species) is the correct answer.

5. **Final Answer**:
- Therefore, the correct answer is **B) 22% of total species**.
