Long distance transport of organic compounds in a plant from a source to a site is known as ……………………...

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the term used to describe the long-distance transport of organic compounds in a plant from a source to a site.

2. **Identifying Key Terms**: In plant biology, the terms "source" and "sink" are crucial. The "source" is where organic compounds (like sugars) are produced (e.g., leaves), and the "sink" is where these compounds are utilized or stored (e.g., roots, fruits).

3. **Transport Mechanism**: The transport of organic compounds in plants primarily occurs through a specialized tissue called phloem. This tissue is responsible for the movement of sugars and other organic molecules.
