Canola (oilseed rape) plants have been genetically modified (GM) to carry a gene that makes them resistant to glufosinate.
A farmer can increase the yield of canola seeds by:
Explain how the use of GM canola plants and the spraying of glufosinate can increase the yield of canola seeds.
Suggest two reasons why some people are concerned about the cultivation or consumption of GM canola plants. Do not refer to ethical concerns or religion in your answer.
