SUMMARY

The discussion focuses on the factors influencing cell division, emphasizing the role of growth factors and cyclin-dependent kinases (Cdks) in both single-celled and multi-celled organisms. Growth factors, also known as mitogens, are essential for activating intracellular signaling pathways that facilitate cell division. The cell-cycle control system, regulated by Cdks, orchestrates the various events necessary for successful cell division. Understanding these mechanisms is crucial for insights into cellular growth and development.

PREREQUISITES
  • Basic understanding of cellular biology

I just learned that cells can divide themselves to develop to higher levels, but I am wondering as to why they can divide themselves, or to be clearer about my wonder, what factors contribute in the division of a cell ?
A catalyst can accelerate a chemical reaction's speed, what enzymes can help cell's division much faster ?
Thank you,
Regards,

Well, in single-celled organisms cell growth requires only nutrients. In multi-celled organisms cell growth and cell division depend on signals from other cells, which are called growth factors or mitogens (for mitosis). These growth factors bind to receptors on the cells surface and activate intracellular signalling pathways.

Inside the cell there is a cell-cycle control system that is regulated by cyclin-dependent kinases (Cdks = protein kinases), which trigger the separate events of division. The process is very complicated, but with experiments they've been able to unravel it to great detail :)
 
Thanks aagain, :)
