Options

A. Absent
B. Unisexual but on different plants
C. Bisexual
D. Unisexual but on the same plant

Answer

**Step-by-Step Solution:**

1. **Understanding Flower Types**:
- Flowers can be classified into two main types: unisexual and bisexual.
- Unisexual flowers contain either stamens (male reproductive parts) or carpels (female reproductive parts), while bisexual flowers contain both.

2. **Identifying Maize Flower Characteristics**:
- Maize (Zea mays) is a plant known for having unisexual flowers. This means that the flowers on the maize plant will either have male or female reproductive structures, but not both in the same flower.

3. **Determining Flower Arrangement**:
- In maize, the unisexual flowers are present on the same plant. This means that while one flower may be male (staminate), another flower on the same plant will be female (pistillate).

4. **Evaluating the Options**:
- Option 1: "Absent" - This is incorrect because maize does have flowers.
- Option 2: "Unisexual but on different plants" - This is incorrect because the unisexual flowers are on the same plant.
- Option 3: "Bisexual" - This is incorrect because maize does not have bisexual flowers.
- Option 4: "Unisexual but on the same plant" - This is correct as maize has unisexual flowers that occur on the same plant.

5. **Conclusion**:
- The correct answer is option number 4: "Unisexual but on the same plant."
