At its heart, this research uncovers the hidden geometric principles behind the unique shape of rose petals. While scientists extensively studied shape morphing in natural sheets such as leaves and ...
Rose petals' unique shapes come from stress during growth. Differential growth and mechanical stresses create curled edges. Research shows petals violate a mathematical condition, causing stress.
Why do rose petals have rounded ends while their leaves are more pointed? In a new study published April 30 in the open access journal PLOS Biology, scientists from the John Innes Centre and ...
