Topic: Classification<\/strong><\/p>\n\n\n\n

What is classification?<\/em><\/p>\n\n\n\n

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.<\/p>\n\n\n\n

1) Animalea <\/strong>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. <\/p>\n\n\n\n

The animal kingdom contains many phyla. Some of them are:\u00a0
Vertebrates, Arthropods, Annelids, Molluscs, Nematodes<\/strong>.\u00a0<\/p>\n\n\n\n

2) Plantae<\/strong> 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\u00a0chlorophyll<\/strong>. Chlorophyll absorbs\u00a0energy<\/strong>\u00a0from sunlight for plant to make\u00a0glucose<\/strong>, using\u00a0CO2<\/strong>\u00a0and\u00a0H2O<\/strong>\u00a0from environment. This is called\u00a0photosynthesis<\/strong>. They also have a unique gas exchange system; they take in carbon dioxide and release oxygen<\/p>\n\n\n\n

3) Fungi<\/strong> 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.<\/p>\n\n\n\n

4) Protista<\/strong> are eukaryotic and have a cell wall. They are both unicellular and multicellular; they are heterotrophic and autotrophic.<\/p>\n\n\n\n

5) Monera<\/strong> are prokaryotic and unicellular. They do not have organelles which are seen in eukaryotes. They are very small compared to most eukaryotes; they also have cell walls and are autotrophic, they use photosynthesis and chemosynthesis to get energy. Some monera can carry out photosynthesis. The oldest fossils belong to this kingdom, so we think that they were the first kinds of organisms to evolve.\u00a0<\/p>\n\n\n\n
