Place a few drops of water containing the slipper-animalcule on a slide with a few fibres of cot- ton and examine with a higher power of the microscope. Is the body divided into parts or cells .â " 3. Do you see the movement of cilia} On what part of the body are they situated .' 4. Do you find a groove sur- rounded by cilia.'
