Expert Answer:

  1. Tapeworms are parasites and their body walls absorb the digested food from the host animal in which they live. So, they do not need a digestive tract.
  2. Protists have flagella, cilia which are all the forms of appendages. They are used for locomotion and, in the case of pseudopodia, for engulfing food (endocytosis).
