Why is it important for bees to attract bright colored flowers

What is the difference between self-pollination and cross-pollination? If pollen is transferred from the stamens of a flower to the stigma of the very same flower, is that cross-pollination or self-pollination? If it is transferredfrom the stamen of one flower to the stigma of another flower on the very same plant? If it is transferred from the stamen of one flower to the stigma of another flower on a different plant, but a plant that is a clone of the first one? Animals do not have pollen, of course, but why is it that most animals never have to worry about the equivalent problem of self-fertilization? Why cannot most animals fertilize themselves?

Which statement about wind-pollinated plants is correct?   Their stamens and stigmas are inside the flower and, compared to insect-pollinated plants, they have large petals   Their stamens and stigmas are outside the flower and, compared to insect-pollinated plants, they have small petals   Their stamens and stigmas are outside the flower and, compared to insect-pollinated plants, they have large petals
