There's no "scientific explanation" for that, at least partly because it doesn't happen.
Girls fall in love because flowers are beautiful and signifies if a man gives you flowers, he thinks your beautiful, and girls adore that.
Flowers smell lovely and die after a week or so. Chocolates taste wonderful and stay on the thighs forever. Your choice. I prefer a personally written poem read to me by my love. It depends on the girl. For girls who have bad allergies, chocolates would be better, but girls who are actively trying to watch their weight may prefer flowers. Answer Personally, I prefer flowers. Nothing to me is more romantic than getting flowers from a man. I can buy chocolates anytime.

get them flowers or chocolates and tell them that you like them and be a sweet/loving guy... tell them how beautiful you think they are
Personally, I think chocolates are better than flowers for guys...I think guys would enjoy that more. Girls love flowers though. It also depends on if this guy is your boyfriend or your husband.
I'm not sure if there is one thing that every girl in the world likes, but some you can safely assume they will like are: chocolates, flowers and compliments.
chocolates
if that girl is your girlfriend you can gift her some nice flowers some chocolates and something she likes very much. if that girl is a friend you ofer her to go to a concert with her
Guy should simply buy flowers and chocolates for girls.
I don't recommend it unless he's really into agriculture and this would be some sort of particularly appropriate flower arrangement. Overall, this is a no. Flowers are for girls, but chocolates are for everyone.
Girls want or need their boyfriends to be supportive, loving, appreciative, respectful, funny, friendly etc. The best way to show a girl you love her is to buy her something special. Whether it be chocolates, or flowers, anything that will make her smile.
Girls dream of that perfect guy. You know the one that holds her tight and kisses her in front of his friends without feeling embarrassed. The guy that gets her flowers,not a pack of condoms or a box of chocolates. Yeah that's what we dream of. COUGH COUGH CHOKE!
