Angle meristem is found in

Options

A. funaria
B. marsilea
C. dryopteris
D. selaginella

Answer

**Step-by-Step Solution:**

1. **Understanding Angle Meristems**: Angle meristems are a type of meristematic tissue found in certain plants. They are responsible for the growth in thickness or girth of the plant.

2. **Location of Angle Meristems**: These meristems are specifically located in the dorsal (upper) and ventral (lower) areas of the plant.

3. **Specific Plant Examples**: Angle meristems are particularly associated with the plant genus *Selaginella*. This genus is known for its unique developmental property called plasticity.

4. **Definition of Plasticity**: Plasticity refers to the ability of plants to adapt their growth and development in response to environmental conditions. This means that *Selaginella* can exhibit a flexible growth pattern.

5. **Comparison with Other Plants**: Other plant types mentioned, such as *Funaria*, *Malsinaria*, and *Dryopteris*, do not have angle meristems. Instead, they possess intercalary meristems, which are located at the nodes and internodes of the plant.

6. **Conclusion**: Therefore, angle meristems are specifically found in *Selaginella*.

**Final Answer**: Angle meristems are found in *Selaginella*.
