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.
