The first time that I heard
about weed killer this question popped in my mind, How does a
weed killer know which one is a good plant and which one is a
weed? Actually what is the difference between weeds and other
plants? They are all plants (as far as I know).
So this project is a good
opportunity for me to find out the difference between weeds and
other plants. Also, I will find out if weed killers can clearly
distinguish between weeds and other plants, because if they don't,
other plants will also get hurt or get killed by weed killers.
