1. Types of Movement

  • Movement is mainly of four types: amoeboid, flagellar, ciliary, and muscular.
  • Amoeboid movement is seen in Amoeba. Temporary cytoplasmic projections called pseudopodia help in locomotion and feeding.
  • Flagellar movement is best seen in Euglena. Flagella are thread-like projections on the cell surface and act as locomotory organelles.
