Question

Describe the functions of the main organs and systems in plants and animals and relate to this their structure 1)petals ,anther,filament and pollen for plant pollination

Answer 1

Petals: The main function of petals is to attract pollinators

Anther: It produces and contains pollen, the male sperm in plants.

Filament: it's the sterile part of the male reproductive organ, and its main function is to sustain the anther.

Pollen: it's the grain that is produced by plants that have flowers (angiosperms), it's the male germinate cell, analogous to spermatozoon in animals.

All these organs are part of the reproductive system in plants, and are not present in animals. But we can make analogies to some of these structures with the animal reproductive system as we did with pollen and spermatozoon
