Question 10

Write one similarity and one difference between the nutrition in amoeba and human beings.

Answer

Similarity: Amoeba and humans are heterotrophs. This means we need to derive energy from other organic sources of carbon.

  • The digestive juices in amoeba are secreted into foods vacuole and in human beings the digestive juices are secreted in stomach and small intestine. Then the juices convert complex food into simpler soluble and absorbable substances.
  • An amoeba is like a human being because they are both living things made of the same elements, similar macromolecules, and cells.

Difference: Amoeba captures the food with the help of pseudopodia and engulf it. In human beings food is taken by the mouth.

  • Human beings have complex structure for the complete process of nutrition involving the following steps ingestion, digestion and egestion of food while Amoeba has a simple process in which it engulfs the food with the help of pseudopodia and traps it in food vacuoles. Though amoeba and humans share the same mode of nutrition, both process the nutrients and convert them into energy in different ways.
