To be exact, seaweed is a type of multicellular algae, and true algae like seaweed belong to the kingdom Protista (not the kingdom Plantae). Algae are simple, plantlike organisms that are believed to be ancestors of modern-day land plants. Lacking vascular tissues like xylem and phloem, pl...
The Animal Kingdom evolved somewhere between 700 million and 1 billion years ago from single celled Protista. Land snails like many species are the product of more than 3 billion years of evolutionary change. The earliest gastropods were exclusively marine, but by the Mesozoic Era,about 248 milli...
Parasitic castratorsbring about a loss of reproductive ability in their hosts. The parasitic castrators use up the reproduction resources of their hosts. Some examples of these parasites include juvenile helminths and some kinds of barnacles. ...
In the late 1930s American botanist Herbert F. Copeland proposed a separate kingdom for the bacteria (kingdom Monera), based on their unique absence of a clearly defined nucleus. Under Copeland’s arrangement, the kingdom Protista thus consisted of nucleated life that was neither plant nor ...
algae, members of a group of predominantly aquatic photosynthetic organisms of the kingdomProtista. Algae have many types oflife cycles, and they range in size from microscopicMicromonasspeciesto giantkelpsthat reach 60 metres (200 feet) in length. Their photosynthetic pigments are more varied than...
Pokémon fill all the requirements of being animals except for their diets. We are still learning much about many strange metabolisms and food preferences in the animal kingdom, so I don’t think we can exclude Pokémon from Animalia just for this, as I mentioned above. We’ll keep explorin...

In marine strata, index fossils that are commonly used include the single-celled Protista with hard body parts and larger forms such as ammonoids. In terrestrial sediments of the Cenozoic Era, which began about 65.5 million years ago, mammals are widely used to date deposits. All of these ...
Fungi are eukaryotic organisms that are classified in their ownKingdom, called Fungi. Thecell wallsof fungi contain chitin, a polymer that is similar in structure to glucose from which it is derived. Unlike plants, fungi don't have chlorophyll so are not able to make their own food. Fungi ...
New reproductive termites are winged so they can fly. These young kings and queens, called alates, leave their home colony and fly out in search of a mate, often in large swarms. Each royal pair of king and queen emerges from the swarm together and finds a new place to start a new co...
