Auxin is primarily synthesized in the shoot apical meristem 🌱 (the growing tips of shoots), young leaves 🍃, and developing seeds.
Key Points:
- Shoot Apical Meristem: The tip of the growing shoot, where rapid cell division occurs, producing new cells that elongate and differentiate.
- Young Leaves: These are actively growing and help in the production of auxin during early development.
- Developing Seeds and Fruits: Auxin is also produced in seeds, influencing fruit development and other growth processes.
Auxin then moves down the plant, playing a crucial role in regulating growth, cell elongation, and directional responses like phototropism (growing towards light) and gravitropism (growing in response to gravity).
