Membrane

Mnemonic

Under the moon, a giant sunflower unfurls petals so impossibly thin they merge into a single translucent membrane. Moonlight filters through this living membrane, casting golden-veined shadows on the ground—like light passing through a delicate cell wall.
Additional thoughts
Picture the moon glowing behind a sunflower whose petals have fused into one continuous, semi-transparent film. The biological feel of 'cell wall' reinforces the tissue/barrier sense of the kanji.
Quick recall
The moon shines through a sunflower's petal-thin membrane.
