             life processes and the variety of living organisms 

1.1

Understand that living organisms share the following characteristics


  • most of all living orgainsms have eigth life process in comoon 
  • nutrition they require food to stay alive 
  • excertion they get rid of waste products 
  • movemenent of all or parts of the orgainsm 
  • growth and devlopment  
  • respiration getting energy from food 
  • responding to stimuli changes in the surrounding 
  • reporoduction producting offspring 
  • controling their internal enviroment 

   living organisms 

  • all living orgainms have eight life process in common 
  • all living organisms are made from tiny bulidng blocks called cells 
  • some organisms have lots of cells they are called muliticellular 
  • some orgainsms consits of single cell which are called unicellular 

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

   plants 

  • are muliticellular 
  • they carry out photosynthesis using carbon dixoide and water to make glucose and oxygen 
  • have chloroplast which contians green pigment called chlorophyll which absorbs sun light for photosynthesies 
  • have cell wall made of cellulose which gives the plant support and strength 
  • store carboyhdrate as starch and sucrose 

 examples include

  • flowering plants such as cereals e.g maize 
  • grasses 
  • sunflower
  •  herbaceous legume (e.g. peas or beans).

animals 

  • are multicellular 
  • are organisms which can not carry out photosynthesis as they do not have chloroplast which contians chlorophyll 
  • animal cells do not have cell wall 
  • most animals
