Sources produce sugars through photosynthesis that are essential for plant growth and development.
Sugars generated in the sources are transported to sinks (areas of storage or growth) via the phloem.
Source activity can change with seasons; for example, leaves act as sources during the growing season.
The efficiency of a source in supplying nutrients affects overall plant health and yield.
Source-sink relationships can be influenced by environmental factors such as light, temperature, and water availability.
