Answer

To determine which of the listed plants have unisexual flowers, we can follow these steps:

### Step 1: Understand the Definition of Unisexual Flowers
Unisexual flowers are those that contain either male (stamen) or female (pistil) reproductive organs, but not both. This means that a unisexual flower will either produce pollen or ovules, but not both.

### Step 2: Identify the Plants
The plants we need to evaluate are:
- Papaya
- Mustard
- Rose
- Corn

2. **Mustard**: Mustard plants have bisexual flowers, meaning they have both male and female reproductive organs.
3. **Rose**: Rose flowers are also bisexual, containing both stamens and pistils.
4. **Corn**: Corn has unisexual flowers. The male flowers are found in tassels, and the female flowers develop into ears.
5. **Petunia**: Petunia flowers are bisexual, containing both male and female parts.
