Answer:
Plants have a cell wall
Explanation:
GMO modification is different for plants and animals because plant cells have cell walls, unlike animal cells.
GMO refers to genetically modified organisms - a technique that involves the introduction of foreign genes into the genome of organisms.
GMO modification requires that the genome of a cell is accessed by a foreign gene and in order to do this, the membrane of the cell has to be disrupted to gain entrance by the gene. Animal cells do not have cell walls, and thus, can be accessed directly relevant mechanisms. Plant cells, however, have cell walls and as such, no direct access to the cell membrane can be achieved without having to remove the cell wall first.
Thus, the cell wall is a major factor that makes GMO modification to be different for plants and animals.
