              2.2      Proses Hidup Organisma Unisel
                       Living Processes in Unicellular Organisms

             1.  Organisma   unisel   ialah organisma yang terdiri daripada   satu   sel sahaja.  TP  2
                 Unicellular   organisms are   single  -celled organisms.

             2.  Organisma ini boleh menjalankan semua proses   hidup   dalam satu sel:  respirasi  ,  nutrisi  ,   pergerakan  ,
                pembiakan  ,   pertumbuhan  ,   perkumuhan   dan   bergerak balas terhadap rangsangan  .  TP  2

               These organisms are able to perform all   living   processes within a cell:   respiration  ,   nutrition  ,   movement  ,
                reproduction  ,   growth  ,   excretion   and   response towards stimuli  .

             3.  Contoh organisma unisel: Amoeba sp. dan Paramecium sp.:  TP  2
               Examples of unicellular organism: Amoeba sp. and Paramecium sp.:
