Most herbaceous plants have how much dry weight of its total fresh weight?

Options

A. 0.92
B. 10 - 15%
C. 0.5
D. 0.29

Answer

To solve the question regarding the dry weight of herbaceous plants in relation to their total fresh weight, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Fresh Weight**:
- Fresh weight of a plant includes both the dry weight (the weight of the plant without water) and the weight of the water contained in the plant.
- Therefore, Fresh Weight = Dry Weight + Water Weight.

2. **Identifying the Nature of Herbaceous Plants**:
- Herbaceous plants are generally small, non-woody plants that tend to have a high water content. This means that a significant portion of their fresh weight is due to water.

3. **Estimating Dry Weight Percentage**:
- In herbaceous plants, the dry weight typically constitutes a smaller percentage of the total fresh weight due to their high water content.
- The common range for the dry weight in herbaceous plants is approximately 10-15% of the total fresh weight.

4. **Evaluating Given Options**:
- The options provided include values like 0.92%, 10-15%, and others.
- Based on the understanding that herbaceous plants have a dry weight percentage in the range of 10-15%, we can conclude that this is the correct option.

5. **Final Answer**:
- Therefore, the correct answer to the question is that most herbaceous plants have a dry weight of **10-15%** of their total fresh weight.
