Understanding the Plant Characteristics
To determine the ratio of advanced to primitive characters in the described perennial shrub, let's analyze its features:
Primitive Characteristics:
- Compound Leaves: Compound leaves can be considered somewhat primitive as they are less specialized.
- Solitary Flowers: Solitary flowers are often found in more primitive plant forms compared to clustered or inflorescent arrangements.
- Exalbuminous Seeds: Seeds without endosperm are usually a trait of more primitive plants.
Advanced Characteristics:
- Zygomorphic Flowers: Zygomorphic (bilaterally symmetrical) flowers are an advanced feature as they often indicate adaptation for specific pollinators.
- Epigynous Flower Structure: Epigyny, where the ovary is positioned below the other floral parts, is generally seen in more advanced plants, allowing for greater protection of the ovary and better fertilization success.
- Dichlamydeous Condition: This refers to flowers having both calyx and corolla, which is typical in advanced flowering plants.
- Many Stamens: A higher number of stamens can be considered advanced as it suggests evolutionary complexity and potential for increased reproductive success.
- Multiple Fruits: The formation of multiple fruits is also indicative of advanced reproductive strategies.
Calculating the Ratio:
- Primitive Characters:
- Compound Leaves
- Solitary Flowers
- Exalbuminous Seeds
- Total: 3
- Advanced Characters:
- Zygomorphic Flowers
- Epigynous Structure
- Dichlamydeous Condition
- Many Stamens
- Multiple Fruits
- Total: 5
Final Ratio:
The ratio of advanced to primitive characters is 5:3. However, if we need to express it in simplest terms relative to the provided options, we can approximate this ratio to 3:2.
Correct Answer: (d) 3:2
