Calcium – Boron – Inositol – Sugar complex

Chemotropic attraction in pollen germination
- In the process of pollen germination, chemotropic attraction plays a crucial role in guiding the pollen tube towards the ovule for fertilization.
- The complex responsible for governing this chemotropic attraction is composed of Calcium, Boron, Inositol, and Sugar.

Role of each component in the complex
- Calcium: Calcium ions are essential for regulating various cellular processes, including pollen tube growth and guidance.
- Boron: Boron is known to be involved in the regulation of cell wall structure, which is crucial for pollen tube elongation and directionality.
- Inositol: Inositol is a signaling molecule that helps in coordinating various cellular responses, including pollen tube guidance.
- Sugar: Sugars provide energy for pollen tube growth and play a role in signaling pathways that regulate pollen tube guidance.

Conclusion
- The Calcium – Boron – Inositol – Sugar complex governs the chemotropic attraction in pollen germination by regulating various cellular processes essential for pollen tube growth and guidance.
