The number of common characters among organisms

Options

A. Decreases ( Angiospermae to Triticum )
B. Increase ( Monocotyledone to Plantae
C. Increases ( sapindales to Angiospermae)
D. Decreases ( poaceae to Plantae )

Answer

To solve the question regarding the number of common characters among organisms, we will analyze the relationships between different groups of organisms and how their common characteristics change during the course of evolution.

### Step-by-Step Solution:

1. **Understanding the Groups**:
- We need to identify the groups mentioned in the options:
- Angiospermae (flowering plants)
- Triticum (wheat)
- Monocotyledonous plants
- Plantae (the plant kingdom)
- Sapindales (a group of flowering plants)
- Poaceae (the grass family)

2. **Analyzing the First Option (Angiospermae to Triticum)**:
- Angiospermae is a broad category that includes all flowering plants.
- Triticum, being a specific species (wheat), has more specific characteristics.
- As we move from a broad category (Angiospermae) to a specific species (Triticum), the number of common characters actually **increases** because Triticum shares characteristics with all angiosperms.

**Hint**: Consider the specificity of the groups; broader groups generally have more common characteristics.

3. **Analyzing the Second Option (Monocotyledonous to Plantae)**:
- Monocotyledonous plants are a subgroup of Plantae.
- Plantae is a larger kingdom that includes all types of plants.
- Moving from a specific group (Monocotyledonous) to a broader category (Plantae) means that the common characters **increase**.

**Hint**: Larger groups encompass more characteristics than smaller, specific groups.

4. **Analyzing the Third Option (Sapindales to Angiospermae)**:
- Sapindales is a specific order of flowering plants, while Angiospermae is a broader category.
- The common characteristics between these two groups would **increase** as well, since Sapindales is a part of Angiospermae.

**Hint**: Remember that moving from a specific order to a broader category generally leads to an increase in common traits.

5. **Analyzing the Fourth Option (Poaceae to Plantae)**:
- Poaceae (the grass family) is a specific family within the Plantae kingdom.
- As we move from a specific family (Poaceae) to the broader kingdom (Plantae), the number of common characteristics **decreases** because Poaceae represents a more specialized group compared to the diverse characteristics found in Plantae.

**Hint**: Think about how specialization in a family can lead to fewer common traits with a broader category.

### Conclusion:
The correct answer is that the number of common characteristics among organisms **decreases** when moving from Poaceae to Plantae.

### Final Answer:
The number of common characters among organisms decreases from Poaceae to Plantae.
