In seeds, digestion is made possible at relatively low temperature by

Options

A. Proteins
B. Enzymes
C. Auxins
D. Nitrogenous complex substances

Explanation

To answer the question "In seeds, digestion is made possible at relatively low temperature by," we need to analyze the role of various components mentioned in the context of seed germination and digestion.

### Step-by-Step Solution:

1. **Understanding Seed Germination**:
- Seeds germinate in the soil, where the temperature is generally low (around 5°C to 8°C). This low temperature can affect metabolic processes, including digestion.

2. **Role of Enzymes**:
- Enzymes are biological catalysts that speed up chemical reactions, including those involved in digestion. They are crucial for breaking down complex molecules into simpler ones that can be absorbed by the seed.

3. **Types of Enzymes Involved**:
- Various enzymes such as amylase (which breaks down starch), protease (which breaks down proteins), and peptidase (which breaks down peptides) are present in seeds. These enzymes facilitate the digestion of stored nutrients in the endosperm and cotyledons, providing energy and building blocks for the growing seedling.

4. **Conclusion**:
- Given that enzymes are responsible for digestion at low temperatures, the correct answer to the question is **enzymes**.

### Final Answer:
In seeds, digestion is made possible at relatively low temperature by **enzymes**.
