Answer:
The instructions for making proteins are coded in the ADN and ARN of a cell. In a eukaryotic cell, these instructions are located in the nucleus .

Plants need nitrogen from the soil to do photosynthesis and produce carbohydrate. The amount of nitrogen is limited but bacteria can synthesis it, giving the plant ingredients that they need. In return, the plant provide carbohydrate to the bacteria. This is a mutualistic symbiosis because they both gain profit for the cooperation.
