The budsites need direct light. Not the leaves.
seriously ?
leaves:
Its main functions are photosynthesis and gas exchange. A
leaf is often flat, so it absorbs
the most light, and thin, so that
the sunlight can get to
the chloroplasts
in the cells. Most
leaves have stomata, which open and close. They regulate carbon dioxide, oxygen, and water vapour exchange with
the atmosphere.
Flowers (budsites):
The primary purpose of a
flower is reproduction. Since the
flowers are the reproductive organs of
plant, they mediate the joining of the sperm, contained within pollen, to the ovules — contained in the ovary. Pollination is the movement of pollen from the anthers to the stigma.
