Opening of flowers in the inflorescence of carrot

Options

A. Centrifugal
B. Basipetal
C. Acropetal
D. Centripetal

Answer

To determine the pattern of flower opening in the inflorescence of carrot, we need to analyze the types of flower arrangements and their respective opening sequences. Here’s a step-by-step solution:

### Step 1: Understand the Types of Flower Opening
There are different types of flower opening patterns in inflorescences:
- **Centrifugal**: Older flowers open first, starting from the outer periphery and moving inward.
- **Centripetal**: Younger flowers open first, starting from the inner part and moving outward.
- **Acropetal**: Younger flowers open first, starting from the top (apex) and moving downward.
- **Basipetal**: Older flowers open first, starting from the bottom and moving upward.

### Step 2: Identify the Inflorescence Type in Carrot
Carrots have an inflorescence type known as an **umbel**. In an umbel, flowers are arranged in a flat-topped cluster, with stems of nearly equal length radiating from a common point.

### Step 3: Analyze Flower Opening in Umbels
In the case of umbel inflorescences, the flowers at the outer edge tend to bloom first, while the inner flowers bloom later. This indicates a **centrifugal** pattern of flower opening.

### Step 4: Conclusion
Based on the analysis, the opening of flowers in the inflorescence of carrot follows a **centrifugal** pattern, where the outer flowers open before the inner ones.

### Final Answer
The opening of flowers in the inflorescence of carrot is **centrifugal**.
