We are Flowers not Fungi

We need sunlight
for there is a brighter world, a brighter side to everything.
We are fostered and we flounder under sunshine.

We are not fungi
for we do not thrive under rocks and dark, wet crevices.
We die alone in the darkness for no one else wants to join.

Edit:
I read my brother this and I asked,

"so are you a flower or fungi?"
and he said flower.

10 minutes later he goes
"no.. i'm a fungi"
"ew"
"fun guy"

reminds me of mr. nelson's torturous idiotic bio classes...
my brother=mr. nelson?
