What are Plant Hormones?
Plant hormones, also known as phytohormones, are chemical substances produced in plants that regulate various physiological processes. They play crucial roles in growth, development, and responses to environmental stimuli.
1) Growth of Stem
- The hormone responsible for the growth of the stem is Auxin.
- Auxins promote cell elongation, which is essential for stem growth, particularly in response to light and gravity.
2) Promotion of Cell Division
- The hormone that promotes cell division is Cytokinins.
- Cytokinins stimulate the process of cell division in plant roots and shoots, enhancing growth and development.
3) Inhibition of Growth
- The hormone responsible for inhibiting growth is Abscisic Acid (ABA).
- ABA plays a critical role in stress responses, such as drought, by inhibiting growth and promoting seed dormancy.
4) Elongation of Cells
- The hormone that facilitates cell elongation is also Auxin.
- Auxins promote the elongation of cells in stems and roots, allowing plants to grow taller and access more sunlight.
Conclusion
Understanding plant hormones is essential for comprehending how plants grow and adapt to their environment. Each hormone plays a specific role in regulating processes that are vital for the plant's overall health and development.
