Brief Description of the four kingdoms
Kingdom Fungi:
Organisms under this kingdom are usually unicellular, however, some are multicellular. These eukaryotic organisms are heterotrophic, have no nervous system, and are not motile. Through vegetative spores and mycelial fragmentation they can reproduce asexually and through meiosis they can reproduce sexually. These organisms prefer to live in slightly acidic, and moist environments, and can even live without light or oxygen [26a]! Organisms in this kingdom would include yeasts, mold, and mushrooms.
Kingdom Protista:
The eukaryotic organisms in kingdom Protista are mostly unicellular, but some are multicellular. These organisms have no nervous system, are motile through a source of flagellum or cilia and can reproduce sexually due to the presence of gametes and reproduce asexually through binary fission. While some of these organisms are chemoheterotrophs, others are Phototrophs. These organisms tend to live in environments with water. Some of these organisms would include alveolates, rhizaria, and heterokonts [27a].
Kingdom Plantae:
Eukaryotic multicellular and unicellular organisms under this domain are non-motile. They have no nervous system and are autotrophic through photosynthesis. However, some organisms are partially heterotrophic. They can reproduce asexually through vegetative reproduction, or reproduce sexually through fertilization and meiosis . Some of these organisms would include tulips, sunflowers, daisies and the venus fly trap.
Kingdom Animalia:
These organisms are the most complex organisms in the world. They are eukaryotic and can be either multicellular or unicellular. They have a nervous system and are motile by many different means. They can reproduce sexually through meiosis or asexually through parthenogenesis. They can ingest other animals, making them heterotrophic. These organisms can live almost anywhere. Some organisms under this kingdom would include insects, lizards and mammals.
