2.2 describe the common features shared by organisms within plant, animal, fungi, bacteria, protoctist and virus kingdoms


ORGANISMS
CHARACTERISTIC
Plants

●      multicellular
●      contain chloroplasts: help carry out photosynthesis
●      cells walls made of cellulose
●      store glucose instead of starch: starch is not water soluble, more compact for storage

Animals

●      multicellular
●      consumer: gain nutrition by feeding on animals or plants
●      move by their nervous system
●      store carbohydrates in the form of glycogen

Fungi


●      eg: mushroom, toadstools, mould
●      mycelium, which is made of thread like filaments called hyphae
Bacteria

●      microscopic
●      unicellular: single celled
●      genetic information is stored in cytoplasm, no nucleus
●      decomposer: recycle dead organisms and waste products in the soil and elsewhere
●      bacillus: any rod shaped bacteria
●      coccus: any sphere shaped bacteria
Viruses

●      microscopic
●      infectious → contagious, likely to be transmitted to people
●      protein coat: protein assembled together to protect the virus. DNA and RNA
●      HIV: virus that causes aids
●      DNA: Deoxyribonucleic Acid
●      RNA: Ribonucleic acid
Protoctista


●      microscopic
●      unicellular
●      amoeba: similar to animal cells
●      chlorella: similar to plant cells
●      plasmodium: organism that causes malaria
