Animals plants and fungi. Organisms fall into two general categories. Protista Fungi Animals and Plants.
In multicellular organisms reproduction refers to the production of. All cells whether unicellular or multicellular prokaryotic or eukaryotic simple or complex irrespective of size have the same basic composition. Similar functions in multicellular organisms are carried out by groups of specialised cells forming different tissues.
Unicellular or multicellular autotrophic organisms Contain chlorophyll pigment and carry out photosynthesis For example. To review this topic refer to Classifying and Exploring Life. Video includes the modern cell theory and p.
Sometimes amoeba reproduces by the process called encysting. Since the amoeba was discovered in the 1980s about 200 cases of the infection. Activity 81 The teacher may show a permanent.
