The type of inflorescence wherein the main axis has limited growth and ends in a flower is termed

Options

A. racemose
B. cymose
C. hypanthodium
D. cyathium

Answer

To solve the question regarding the type of inflorescence where the main axis has limited growth and ends in a flower, we can analyze the options provided:

1. **Racemos**: In this type of inflorescence, the main axis continues to grow and does not terminate in a flower. Instead, flowers are arranged in an acropetal manner, meaning the younger flowers are at the top and the older ones are at the bottom. Therefore, this option does not fit the description given in the question.

2. **Cymos**: This type of inflorescence is characterized by limited growth of the main axis, which terminates in a flower. In cymos inflorescence, the younger flowers are located at the base, and the older flowers are at the top, indicating a basibetal arrangement. This matches the description in the question.

3. **Hypanthodium**: This inflorescence type forms a cup-shaped structure that contains both male and female flowers. The main axis does not have limited growth in the same way as described in the question. Therefore, this option is not correct.

4. **Cyathium**: Similar to hypanthodium, cyathium also forms a cup-shaped structure, but it features a single female flower surrounded by numerous male flowers. Again, the main axis does not have limited growth as described in the question.

Based on this analysis, the correct answer is **Cymos**, as it is the type of inflorescence where the main axis has limited growth and ends in a flower.

### Step-by-Step Solution:
1. **Identify the types of inflorescence**: Understand the definitions of racemos, cymos, hypanthodium, and cyathium.
2. **Analyze the characteristics**: Determine the growth patterns of the main axis for each type.
3. **Match with the question**: Look for the type that has limited growth and terminates in a flower.
4. **Select the correct answer**: Conclude that the correct answer is cymos.
