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…
