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/birddroppings/sticky 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

10 Less surface to not waste water
11 Keep the crop at a level he can get to them easily

Answer 2

You could figure out some of these for yourself. I've pick one that I will help you with because it is difficult.

7. Why must some plants be carnivorous?

Because they live in habitats where the soil is low in nitrogen. Some plants deal with this by forming symbiotic relationships with bacteria that fix nitrogen. Carnivorous plants have a different strategy. They eat nitrogen rich insects. The pitcher plant has even been know to trap rodents.

Crack some books or do a web search. You will learn better if you read and figure things out on your own.
