1.2 describe the common features shared by organisms within the following main
groups: plants, animals, fungi, bacteria, protoctists and viruses, and for each
group describe examples and their features as follows (details of life cycle and
economic importance are not required)
Plants: These are multicellular organisms; their cells contain chloroplasts and
are able to carry out photosynthesis; their cells have cellulose cell walls; they
store carbohydrates as starch or sucrose
Examples include flowering plants, such as a cereal (for example maize), and
a herbaceous legume (for example peas or beans)
Animals: These are multicellular organisms; their cells do not contain
chloroplasts and are not able to carry out photosynthesis; they have no cell
walls; they usually have nervous coordination and are able to move from one
place to another; they often store carbohydrate as glycogen
Examples include mammals (for example humans) and insects (for example
housefly and mosquito)
Fungi: These are organisms that are not able to carry out photosynthesis;
their body is usually organised into a mycelium made from…
