Parenchymatous tissue is the site of

Options

A. Photosynthesis
B. Storage of food materials
C. Secretion and excretion
D. All of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Parenchyma Tissue**:
- Parenchyma is a type of simple permanent tissue in plants. It consists of living cells that are generally thin-walled and can vary in shape, often being oval, round, or spherical.

2. **Functions of Parenchyma Tissue**:
- The primary functions of parenchyma tissues include:
- **Photosynthesis**: Parenchyma cells can contain chloroplasts, especially in the leaves, allowing them to perform photosynthesis by converting sunlight into energy.
- **Storage of Food**: These cells have large intercellular spaces which facilitate the storage of food materials and nutrients, making them essential for the plant's energy reserves.
- **Secretion and Excretion**: Parenchyma cells can secrete substances like gums and tannins, which can form protective layers on the plant and help in reducing water loss, especially in dry habitats.

3. **Conclusion**:
- Given the functions mentioned above, parenchymatous tissue is responsible for photosynthesis, storage of food materials, and secretion/excretion. Therefore, the correct answer to the question is **"all of the above."**
