What is the major difference in the production of transgenic bacteria, plants, and animals?
Flauer [41]

Answer:

Transgenic animals require a host to grow but transgenic bacteria and plants do not require host.

Explanation:

Transgenic organisms are the organisms in which foreign genetic material are introduced so that the transgenic organism can get some particular traits and characteristic.

The process of producing transgenic animals is different from producing transgenic plant and transgenic animals because in transgenic animals DNA from a cell is transferred into an enucleated oocyte.  

Then this oocyte is transferred to the oviduct of a surrogate mother to raise the genetically modifies embryo but in plant and microbe, no host is required.

Consequently, it will be difficult for the needed oxygen atoms to simply diffuse into the alveoli to reach the blood,Compare to its  molecular form  where its atoms awere held  by relatively week covalent bonds.

Besides the porosity    of the thin  alveolar endothelial   walls of 0.2 micrometer is   too small for the larger water molecules to pass through.
