Transfer of DNA into host cells- the various methods ...

Gene guns are so far mostly applied for plant cells. However, there is much potential use in animals and humans as well. Plants. The target of a gene gun is often a callus of undifferentiated plant cells growing on gel medium in a petri dish. After the gold particles have impacted the dish, the gel and callus are largely disrupted.

Plant Cell vs Animal Cell - Difference and Comparison | Diffen

A difference between plant cells and animal cells is that most animal cells are round whereas most plant cells are rectangular.Plant cells have a rigid cell wall that surrounds the cell membrane.
