Answer: Louis Pasteur
Louis Pasteur in 1860s, proposed germ theory. The theory was based upon the fact that diseases are caused by the microorganisms.
He was officially the first to publish his work.

The offsprings or children would be very similar to their parents.
Cross over involves the exchange of chromosomes segments between non-sister chromatids during the process of meiosis. It creates new combinations of genes in the gametes that are not found in either parent, a factor that brings about genetic variation or genetic diversity among individuals. Therefore, without crossover offsprings would be genetic similar with their parents.
Cells with a relatively simple cell morphology that do not have a true membrane-delimited nucleus are called Prokaryotes.
What are Prokaryotes?
Any organism without internal membranes is referred to as a prokaryote, usually written procaryote. These organisms lack a defined nucleus and other organelles. One of the most well-known prokaryotic species is bacteria. Prokaryotes differ from eukaryotes by not having internal membranes. The principal osmotic barrier of prokaryotic cells is the membrane, which is composed of phospholipids. Ribosomes, which are responsible for protein synthesis, and a double-stranded circular DNA chromosome are both found in the cytoplasm. The circular DNA units known as plasmids, which are found in many prokaryotes, have extra disposable cell activities such encoding proteins that render antibiotics inactive. Prokaryotes with flagella exist. The flagella present on some eukaryotes differ from prokaryotic flagella in terms of appearance and motion.
The cell wall and cytoskeletal components work together to preserve the morphology in the majority of prokaryotic cells. The majority of prokaryotes and certain eukaryotes have a structure called the cell wall that surrounds the cell membrane and shields it from osmotic pressure changes.
Bacteria are prokaryotic cells, i.e., they do not have a membrane-delimited nucleus. Eukaryotes have cells with a delimited nucleus.
Thus these types of cells are called prokaryotes.
