Monadelphous and monothecous

Options

A. Liliaceae
B. Solanaceae
C. Malvaceae
D. Asteraceae

Explanation

### Step-by-Step Solution:

1. **Understanding Monadelphous Condition**:
- The term "Monadelphous" refers to a condition in flowering plants where the stamens are united by their filaments into a single group. This means that all the filaments of the stamens are fused together, forming a single structure.

2. **Understanding Monothecous Condition**:
- The term "Monothecous" indicates that there is only one anther (the part of the stamen that produces pollen) per stamen. This means that the flower has a single, undivided anther.

3. **Identifying Families with These Conditions**:
- The question asks which plant families exhibit both Monadelphous and Monothecous conditions.
- The **Malvaceae** family is known for having a large number of stamens that are united by their filaments (Monadelphous condition). Additionally, they typically have one anther per stamen (Monothecous condition).

4. **Examples of Other Families**:
- In the **Liliaceae** family, there are usually six stamens that are free, not united (not Monadelphous).
- In the **Solanaceae** family, there are five free stamens (not Monadelphous).
- In the **Asteraceae** family, there are also five free stamens (not Monadelphous).

5. **Conclusion**:
- Therefore, the correct answer to the question about which family exhibits both Monadelphous and Monothecous conditions is the **Malvaceae** family.
