1. ALGAE

   • mostly autothophic
   • requires water
   • sexual&asexual
   • can be unicellular/colonies
   • cell wall made of cellulose fibrils
   • teresterial
   • aquatic
     • planktonic
     • benthic
     • neustonic
   • divided into
     • chlorophyta
     • rhodophyta
     • phaeotphyta

4. INTRO about PROTIST

   • gorw in moist habitat
   • most are unicellular
   • Plasma membrane structure similar to multicellular plants/animals
   • cytoplasm
     • Outer gelatinous ectoplasm
     • endoplasm
   • vacoule commonly present
   • presence of cilia/flagella
   • sexual/asexual
