Agriculture affects every part of our lives from what we eat to what we wear and can even be used to power our cars. Medical research may be good at finding cures for diseases but agricultural research is what is needed to feed the world’s growing population. That’s what makes it an exciting area to specialise in.
Sunflowers can cope with lots more sunlight than most plants but there’s probably a limit. I guess if it goes on for too long the plant will get stressed and if there’s not enough water around it will start to wither. But sunflowers are pretty good at coming back to life if you give them water after a drought.
