ATP (adenotriphosphate) molecules are considered as energy currency of the cells as molecules provide energy for various cellular functions.
The energy is stored in ATPs in two high-energy phosphate bonds, known as phosphoanhydride bonds. This stored energy is released in during hydrolysis of ATP, which involves removal of terminal phosphate groups bound the carbon backbone.
sepals protect inner floral leaves in bud stage of the flower, carry out photosynthesis, attract animal pollinators when petaloid (have same color with petals eg in pride of barbados)
