Frits Went

Definition

Frits Went was a Dutch botanist known for his pioneering work in plant physiology, particularly in the discovery and study of plant hormones. He is best remembered for his research on auxins, a class of hormones that regulate various aspects of plant growth and development, including cell elongation, fruit development, and responses to light and gravity. His work laid the foundation for our understanding of how plants use hormones to communicate internally and adapt to their environment.

5 Must Know Facts For Your Next Test

1. Frits Went is credited with coining the term 'auxin' after conducting experiments with the plant hormone, which demonstrated its effects on plant growth.
2. He developed the agar block method to isolate auxins from plant tissues, enabling a more precise study of their effects on plant growth.
3. Went's research showed how auxins promote cell elongation by influencing cell wall flexibility and growth direction.
4. He contributed to the understanding of how auxins are involved in phototropism, where plants grow toward light sources, optimizing their ability to photosynthesize.
5. Frits Went's work set the stage for further exploration into other plant hormones like cytokinins and gibberellins, expanding our understanding of hormonal interactions in plants.
