The concept presented to explain the origin of eukaryotic cells form a bacterial cell parasitized by another descendant cell is called endosymbiosis.
<h3>What is the endosymbiotic theory?</h3>
The endosymbiotic theory is a well-sustained theory in biology about the origin of eukaryotic cells.
According to this theory, eukaryotic cells emerged by endosymbiosis between primitive eukaryotic cells and bacteria that converted into mitochondria and chloroplast organelles.
The endosymbiotic theory is well sustained in several scientific observations such as the existence of DNA in mitochondria and chloroplasts that is independent of nuclear DNA, the size of ribosomal units, etc.
In conclusion, the concept presented to explain the origin of eukaryotic cells form a bacterial cell parasitized by another descendant cell is called endosymbiosis.

Both glucose and amino acids are needed inside the cells, but these molecules are too big to pass through the cell membrane on their own. Therefore, they need the help of the transport proteins which are located on the membrane of the cells. The transport proteins help both glucose and amino acid to enter the cells through facilitated diffusion.
The synthesis of the organic molecules in the primitive atmosphere would have favored because it was reducing and exhibited sources of energy in the form of UV radiation and lightning.
The biggest constituent of the primitive atmosphere was carbon dioxide, succeeded by hydrogen and nitrogen with almost nil oxygen. This atmosphere resulted mainly from the gases discharged due to cooling of the molten plant and at the time of volcanic eruptions.
