In autumn all leaves fall,but still the heavy flowers bloom .how it happens without photosynthesis thro' leave

Hi,





Some plants produce their flowers before their leaves by using stored energy/food.





Generally, the energy/food was obtained from photosynthesis; however, it took place previously and was then stored by the plant and/or stored by a ';seed'; or bulb. This is the same reason that a plant can grow from a seed/bulb before it has leaves.





I hope this helps you out.
