Identify the plants which show actinomorphic pentamerous flowers, Zygomorphic pentamerous flowers and actinomorphic trimerous flowers respectively

Options

A. Ruscus, Lathyrus, Capsicum
B. Solanum, Phaseolus, Asparagus
C. Datura, Allium, Pterocarpus
D. Gloriosa, Petunia, Pterocarpus

Answer

To identify the plants that show actinomorphic pentamerous flowers, zygomorphic pentamerous flowers, and actinomorphic trimerous flowers, we can follow these steps:

### Step 1: Understand the Definitions
- **Actinomorphic Flowers**: These flowers are radially symmetrical, meaning they can be divided into two equal halves in multiple planes.
- **Zygomorphic Flowers**: These flowers are bilaterally symmetrical, meaning they can only be divided into two equal halves in one specific plane.
- **Pentamerous Flowers**: These flowers have five petals and/or sepals.
- **Trimerous Flowers**: These flowers have three petals and/or sepals.

### Step 2: Identify the Families
1. **Actinomorphic Pentamerous Flowers**:
- These flowers belong to the **Solanaceae** family.
- Example plants: **Capsicum** and **Solanum**.

2. **Zygomorphic Pentamerous Flowers**:
- These flowers belong to the **Fabaceae** family.
- Example plant: **Lathyrus** (also known as sweet pea).

3. **Actinomorphic Trimerous Flowers**:
- These flowers belong to the **Asparagaceae** family.
- Example plant: **Ruscus**.

### Step 3: Summarize the Findings
- **Actinomorphic Pentamerous Flowers**: Solanaceae family (e.g., Capsicum, Solanum).
- **Zygomorphic Pentamerous Flowers**: Fabaceae family (e.g., Lathyrus).
- **Actinomorphic Trimerous Flowers**: Asparagaceae family (e.g., Ruscus).

### Final Answer
1. **Actinomorphic Pentamerous Flowers**: Solanaceae (e.g., Capsicum, Solanum)
2. **Zygomorphic Pentamerous Flowers**: Fabaceae (e.g., Lathyrus)
3. **Actinomorphic Trimerous Flowers**: Asparagaceae (e.g., Ruscus)
