• Answer:

  20 1 genetic engeneering or crossbreeding. 2 to not be eaten. Increase survivability. 3 wind and temperature. Stick your 'head' out and it will freeze/dry out. 4 wind/parachute/springsystem/birddropping… ability 5Less messy and less labourintensive. predictable and continuous crop production and relative low cost. 6The photosynthetic action spectrum depends on the type of accessory pigments present. For example, in green plants, the action spectrum resembles the absorption spectrum for chlorophylls and carotenoids with peaks for violet-blue and red light. In red algae, the action spectrum overlaps with the absorption spectrum of phycobilins for blue-green light, which allows these algae to grow in deeper waters that filter out the longer wavelengths used by green plants. The non-absorbed part of the light spectrum is what gives photosynthetic organisms their color (e.g. green plants, red algae, purple bacteria) and is the least effective for photosynthesis in the respective organisms. 7 Lack of other natural sources 8 http://en.wikipedia.org/wiki/Phototropism 9 http://en.wikipedia.org/wiki/Geotropism 10 Less surface to not waste water 11 Keep the crop at a level he can get to them easily 12 light-dependent reactions and light-independent reactions 13 Keep a diverce genetic profile.
