Edexcel Biology - The nature and variety of living organisms

?
Eight Characteristics of living Organisms
characteristics: • they require nutrition • they respire • they excrete their waste • they respond to their surroundings • they move • they control their internal conditions • they reproduce • they grow and develop.
1 of 7
Describe common features of Plants
Plants: Multicellular organisms Cells contain chloroplasts and are able to carry out photosynthesis Cells have cellulose cell walls Store carbohydrates as starch or sucrose
2 of 7
Describe common features of Animals
Animals: Multicellular organisms Cells do not contain chloroplasts and are not able to carry out photosynthesis No cell walls; they usually have nervous coordination (using nervous system) Able to move from one place to another Store carbohydrate as

Describe common features of Fungi
Fungi: Not able to carry out photosynthesis Body is usually organised into a mycelium made from thread-like structures called hyphae, which contain many nuclei Some examples are single-celled Cells have walls made of chitin Feed by extracellular secr

Describe common features of Protoctists
Protoctists: Microscopic single-celled organisms Some, like Amoeba, that live in pond water, have features like an animal cell Others, like Chlorella, have chloroplasts and are more like plants. A pathogenic example is Plasmodium,responsible for ca

Describe common features of Bacteria
Bacteria: Microscopic single-celled organisms Have a cell wall, cell membrane, cytoplasm and plasmids; they lack a nucleus but contain a circular chromosome of DNA Some bacteria can carry out photosynthesis but most feed off other living or dead orga

Describe common features of a Virus
Viruses: Not living organisms Small particles, smaller than bacteria Parasitic and can reproduce only inside living cells; they infect every type of living organism Wide variety of shapes and sizes No cellular structure but have a protein coat and co
