What is classification?
Classification is the method used divide organisms into separate segments. the segments that the organisms are divided into are called the animal kingdoms. They are divided by the difference in their cellular structure. There are 5 different animal kingdoms – Monera, Protista, Fungi, Plantae and Animalea.
1) Animalea are eukaryotic and not have a cell wall. They have a hormonal and nervous control system; they are heterotrophic which means the can eat and digest food.
The animal kingdom contains many phyla. Some of them are:
Vertebrates, Arthropods, Annelids, Molluscs, Nematodes.
2) Plantae are eukaryotic and multicellular. They have a cell wall; they are autotropic which means they use photosynthesis to make their own energy. Some parts of a plant are green, thanks to pigment chlorophyll. Chlorophyll absorbs energy from sunlight for plant to make glucose, using CO2 and H2O from environment. This is called photosynthesis. They also have a unique gas exchange system; they take in carbon dioxide and release oxygen
3) Fungi are eukaryotic and are also multicellular like animals and plants but unlike them, fungi can be unicellular as well. They have a cell wall and they are heterotrophic and saprotrophic which means they can digest food and are also parasitic.
4) Protista are eukaryotic and have a cell wall. They are both unicellular and multicellular; they are heterotrophic and autotrophic.
This is a the structure of a Protista
