All of the petals of a flower are called a corolla. The calyx, made up of sepals, is located beneath (behind) the corolla. The sunflower is one of those plants that has a flower head. The inner florets have very reduced (small) petals. They will form the fruits/seeds. The outer florets (ray or petal bearing florets) can be yellow, red, orange or a combination of those colors.

The amount of pistils or a rose depends on the variety of a rose. Most roses have several pistils. The pistil is the female reproductive part of a flower.
Yes, there are flowers without pistils. E.g the flower of lemon however, most of flowers have pistils.
Datura plant has two pistils (carpels) in its flower. Both these pistils are united to form one ovary.
A sunflower is a unisexual flower. Flowers that are unisexual have either stamens and no pistils or pistils with no stamens.
Cross-pollinated flowers usually have their stamens higher than their pistils. This is what will make it easer for the pollen grains to fall on the pistils for purposes of pollination

The ovary.
It depends on the type of flower and condition of gynoecium. In a pentamerous flower with apocarpus condition, there may be as many as five pistils but in syncarpous condition there will be only one united structure of all the five pistils.
Pistils grow out of the female buds of a plant to more efficiently catch pollen from the male plant that is floating through the air.
