Answer

To determine the ratio between female to male flowers in a cyathium, we can follow these steps:

### Step 1: Understand what a cyathium is
A cyathium is a type of inflorescence found in the genus Euphorbia. It is characterized by a unique structure that includes a cup-shaped involucre.

**Hint:** Look for the definition of cyathium and its characteristics in botanical literature.

### Step 2: Identify the components of the cyathium
In a cyathium, there is a single female flower located at the center, which is supported on a long stalk. This female flower is surrounded by a large number of male flowers.

**Hint:** Visualize the structure of the cyathium to better understand the arrangement of flowers.

### Step 3: Analyze the arrangement of flowers
The male flowers are arranged centrifugally around the single female flower. This means that there are many male flowers surrounding one female flower.

**Hint:** Remember that "centrifugally" indicates that the male flowers are positioned outward from the center where the female flower is located.

### Step 4: Determine the ratio
Given that there is one female flower and many male flowers, the ratio of female to male flowers in a cyathium is expressed as many to one.

**Hint:** Ratio is expressed as the number of females to the number of males, so think about how many of each type there are.

### Conclusion
The ratio of female to male flowers in a cyathium is many to one.

**Final Answer:** Many ratio one.
