Many insects are attracted to pollen, which they use for food. How does this help flowering plants?

This fertilizes the flower and the plant will then grow seeds and the fruit around the seeds.

Explanation:

Many flowers produce nectar, a sugary liquid that many insects eat.

Explanation:

When an insect lands on a flower to feed, pollen grains stick to its body. As the insect moves to another flower of the same species, these pollen grains are transferred to the flower's stigma and pollination occurs. It can help even more plants grow.

a tetrad is the foursome during meiosis made by two homologous chromosomes that have each already replicated into a pair of sister chromatids.
