Answer

To answer the question "Place of origin of seed coats is known as," we need to analyze the options provided: gelasa, hillum, node, or micropyle.

1. **Understanding Seed Coats**: The seed coat is a protective layer that surrounds the seed. It is formed from the integuments of the ovule, which are the outer layers that protect the developing seed.

2. **Identifying the Origin**: The seed coat originates from the ovule, specifically from the integuments. The place where the integuments attach to the ovule is referred to as the chalaza.

3. **Evaluating the Options**:
- **Gelasa**: This term is not commonly associated with seed coats.
- **Hillum**: This is the scar on the seed where it was attached to the ovule, but it is not the origin of the seed coat.
- **Node**: This term generally refers to a part of a plant stem and is not related to seed coats.
- **Micropyle**: This is the opening in the ovule through which the pollen enters but is not the origin of the seed coat.

4. **Conclusion**: The correct answer is **chalaza**, as it is the place of origin of the seed coats.

**Final Answer**: Chalaza
