Question

Angiosperms are such a successful group of plants because of how well they recruit animals for pollination and the diverse way they disperse their seeds. Describe two ways animals spread angiosperm pollen and two ways fruit is dispersed.

Answer 1

Answer:

- pollen dispersal: insects and birds are able to spread the pollen of flowers for reproduction

- fruit dispersal: many different mammals (including for example mice, kangaroo, and elephants) eat fruits and then disperse their seeds

Explanation:  

Pollination is the process of transfer of pollen (i.e. male gametes) from plant male reproductive structures (called anthers) to the plant female reproductive organ (stigma). For example, hummingbirds pollinate flowers no other animal can (nectar of these flowers is used as food source). Similarly, honey bees pollinate flowers by transferring pollen from the male anther of a flower to the stigma of another flower. On the other hand, many animals (such as, for example, mice) eat different types of fruits and then disperse their seeds by excreting them. In addition, there are fruits with hooks that attach to the hair of many mammals and thus they can be dispersed to far away places.

Answer 2

It should be noted that birds and insects are pollinators and can spread angiosperm.

It should be noted that pollination simply means the process of transferring pollen from the anthers to the stigma.

The ways of dispersing fruits can be through pollen dispersal such as insects and birds spreading the pollen of flowers for reproduction.

Also, it can be through fruit dispersal as many different mammals like bats, kangaroos, etc.
