  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Protozoon  \Pro`to*zo"["o]n\  (-[o^]n),  n.;  pl  {Protozoa}.  [NL.] 
  (Zo["o]l.) 
  a  One  of  the  Protozoa. 
  b  A  single  zooid  of  a  compound  protozoan. 
 
  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Protozoa  \Pro`to*zo"a\,  n.  pl  [NL.,  fr  Gr  ?  first  +  ?  an 
  animal.]  (Zo["o]l.) 
  The  lowest  of  the  grand  divisions  of  the  animal  kingdom. 
 
  Note:  The  entire  animal  consists  of  a  single  cell  which  is 
  variously  modified;  but  in  many  species  a  number  of 
  these  simple  zooids  are  united  together  so  as  to  form  a 
  compound  body  or  organism,  as  in  the  Foraminifera  and 
  Vorticell[ae].  The  reproduction  takes  place  by  fission, 
  or  by  the  breaking  up  of  the  contents  of  the  body  after 
  encystment,  each  portion  becoming  a  distinct  animal,  or 
  in  other  ways,  but  never  by  true  eggs.  The  principal 
  divisions  are  Rhizopoda,  Gregarin[ae],  and  Infusoria. 
  See  also  {Foraminifera},  {Heliozoa},  {Protoplasta}, 
  {Radiolaria},  {Flagellata},  {Ciliata}. 
 
  From  WordNet  r  1.6  [wn]: 
 
  Protozoa 
  n  :  in  some  classifications  considered  a  superphylum  or  a 
  subkingdom;  comprises  flagellates;  ciliates;  sporozoans; 
  amoebas;  foraminifers  [syn:  {Protozoa},  {phylum  Protozoa}]
