Discussion

  • It is a microscopic, unicellular entity with a diameter of 0.2-0.5mm, appearing greyish in colour.
  • The amoeba is usually found in ditches, ponds, lakes or rivers that contain adequate decomposed organic matter.
  • When observed under a microscope, amoeba seems to be like a jelly that has an irregular shape containing a little mass of hyaline protoplasm. This protoplasm can be classified into a notable inner endoplasm and outer octoplasm.
