Please give the names of the major extensions of the cell surface?

@ joe 
endocytosis and endosmosis are the two major extensions of the cell surface . 
in endocytosis the cell will engulf the particle which can be either food particle or raw material . 
it occurs by infolding of cell surface through vescicles . 
example – endocytoosis occurs thriough pseupodia in amoeba , 
HOPE IT CLEARS YOUR DOUBT 
ALL THE BEST ..

The major extensions of cell surface are pseudopodia, filopodia, lamellipodia, microvilli, etc.. Some of these can be seen only during cellular movements.

 

Hope you got the answer.
