Answer

To determine the species diversity of plants on Earth, we need to analyze the given options and understand the concept of species diversity. Here’s a step-by-step breakdown:

### Step 1: Understand Species Diversity
Species diversity refers to the variety of different species within a given ecosystem or on the entire planet. It includes two main components:
- **Species Richness**: The total number of different species present in a community.
- **Species Evenness**: The relative abundance of each species in a community.

### Step 2: Analyze the Given Options
The options provided for the species diversity of plants are:
1. 0.02424
2. 0.22
3. 0.081
4. 0.85

### Step 3: Identify the Correct Percentage
From the information provided, it is mentioned that the species diversity of plants on Earth is approximately 22%. This means that out of the total biodiversity, plants account for 22%, while the remaining 70% is comprised of animals.

### Step 4: Convert Percentage to Decimal
To match the options given, we convert 22% into decimal form:
- 22% = 22/100 = 0.22

### Step 5: Conclusion
Based on the analysis, the species diversity of plants on Earth corresponds to the option 0.22.

### Final Answer
The species diversity of plants on Earth will be **0.22**.
