Which of the following are the important floral rewards to the animal pollinators?

Step-by-step solution

The important floral rewards to the animal pollinators are nectar and pollen grain. Plants attract pollinators to their flowers by advertising their floral rewards, i.e., nectar and pollen grain. They take the advantage of the fact that the animals can see, smell and taste by evolving different flower sizes, shapes, colors and scents to selectively attract pollinators.
