Answer;

Nucleus

Micropipettes and gene guns are mechanical vectors that introduce recombinant DNA directly into the cell’s nucleus of a host cell.

Explanation;Micropipettes are used to transfer very small and exact volumes of liquids in either milliliters or microliters, which are the measurements of volume most often used in genetic engineering.Microinjection is the process of using micropipette to inject liquid substances at microscopic level.The process is used to introduce a vector into a single cell in recombinant DNA technology. It may also be used in cloning of organisms.

Leaves specifically the gas exchange between plants and the environment. while plants undergo photosynthesis, they also partake in cellular respiration. respiration is the process that happens in the leaves of plants.
