White and red Aster flowers in the garden in the greenery

White and red Aster flowers in the garden in the greenery.The flower is a modified, shortened and limited in growth spore-bearing shoot, adapted for the formation of spores and gametes, as well as for the sexual process, culminating in the formation of a fruit with seeds. The exceptional role of the flower as a special morphological structure is due to the fact that it completely combines all the processes of asexual and sexual reproduction. The flower differs from the cone of gymnosperms in that pollination results in pollen falling on the stigma of the pistil, and not on the ovary directly, and during the subsequent sexual process, the ovaries of the flower develop into seeds inside the ovary.
