Schizogenous cavity is seen in

Options

A. Helianthus
B. Pinus
C. Cucurbita
D. Both 1 and 2

Answer

### Step-by-Step Solution:

1. **Understanding Schizogenous Cavities**:
- Schizogenous cavities are spaces that form between plant cells due to the separation of cell walls. This process occurs during the development of certain tissues in plants.

2. **Identifying Where Schizogenous Cavities are Found**:
- These cavities are typically found in the intercellular spaces of specific plant types, particularly in certain aquatic plants and some monocotyledons.

3. **Function of Schizogenous Cavities**:
- The primary functions of these cavities include the storage of water, gases, or secondary metabolites. This is crucial for the plant's survival, especially in aquatic environments where buoyancy and gas exchange are important.

4. **Conclusion**:
- Based on the information, we can conclude that schizogenous cavities are seen in aquatic plants and some monocotyledons, serving important functions related to storage and gas exchange.
