PATHOLOGY

Detailed explanation-1: -Cells are the smallest units (or most basic building blocks) of life, and all cells come from preexisting cells through the process of cell division. Life cannot be created in a laboratory.

Detailed explanation-2: -The third part, which asserts that cells come from preexisting cells that have multiplied, was described by Rudolf Virchow in 1858, when he stated omnis cellula e cellula (all cells come from cells).

Detailed explanation-3: -Yes, all living cells arise from pre-existing cells through division. Prokaryotic cells produce genetically identical daughter cells through binary fission. In an eukaryotic organism, namely an animal, a new zygote is produced through fertilization of a haploid egg by a haploid sperm.

Detailed explanation-4: -When this long-standing myth was finally dispelled in the mid-1800s, it became clear that all life must arise from pre-existing life — via a process of reproduction. If cells are the fundamental units of life, they too must have a reproductive mechanism that maintains the proper chromosome number in each cell.
