Characteristics of living organisms include;M ovement;R espiration;S ensitivity;G rowth;R eproduction;E xcretion;N utrition;Living organisms are classified into 5 groups, each of which has certain characteristics you need to learn;Plants;1. Multicellular organisms;2. Cells contain chloroplasts and are able to carry out photosynthesis;3. Cells have cellulose cell walls;4. They store carbohydrates as starch or sucrose.;Examples include flowering plants, such as a cereal (e.g. maize) and a herbaceous legume (e.g. peas or beans).;Animals;1. Multicellular organisms;2. Cells do not contain chloroplasts and are not able to carry out photosynthesis;3. Cells have no cell walls;4. They have a nervous system;5. They often store carbohydrate as glycogen;Examples include mammals (e.g. humans) and insects (e.g. housefly).;Fungi;1. They are saprophytic and feed by excreting digestive enzymes onto food and absorbing the digested products;2. Cells do not contain chloroplasts and are not able to carry out photosynthesis;3. Cells are joined together to form threads, called hyphae. Hyphae contain many nuclei, because they are made from many cells.;4. Cell walls are made from chitin (a protein);5. They store carbohydrates as glycogen.;Bacteria;1. Made from single cells;2. Cells do not contain a nucleus, but have a small piece of circular DNA instead (a bacterial chromosome).;3. Some bacteria can carry out rudimentary photosynthesis, but most are saprophytes;4. They have the structure below (learn it, it comes up!);Protoctisis;Basically, everything that doesn't fit into the other kingdoms! Most are single celled organisms which can either;1. Have animal-like characteristics (e.g. Amoeba);2. Have plant-like characteristics (e.g. Chlorella);Viruses;1. Much smaller than bacteria. They are not made from cells;2. Totally parasitic and reproduce inside host cells;3. They infect every type of living cell;4. They have the structure below (learn it, it comes up!);THIS ONE PRESENTATION I WANT TO DO POSING QUESTION ON IT,, A SMALL SUMMERY AND THEN A GOOD QUESTION.
