Which cellular function provides evidence for the portion of the cell theory that states “all cells come from pre-existing cells
The process of cell division, specifically through mitosis and meiosis, provides evidence for the portion of the cell theory that states "all cells come from pre-existing cells."
During mitosis, a parent cell divides into two identical daughter cells, each containing the same genetic material as the parent cell. This process of cell division ensures the continuity and growth of an organism's cells. Meiosis, on the other hand, involves the formation of sex cells (gametes) with half the genetic material of the parent cells. This process is responsible for sexual reproduction and the creation of genetically diverse offspring.
Both mitosis and meiosis demonstrate that cells are capable of replication and the generation of new cells. This supports the idea that all cells come from pre-existing cells, as these processes involve the division and distribution of cellular components to create new, functional cells.
