Question 10
Write one similarity and one difference between the nutrition in amoeba and human beings.
-Similarity: The basic process of digestion of food and release of energy is the same in amoeba as well as in human beings. Both have holozoic mode of nutrition. In amoeba, digestive juices are secreted into the food vacuole. They act on the food and break it down into simpler substances. Gradually the digested food is absorbed. Similarly, in human beings various digestive juices act on food and break it down into simpler substances.
- Difference: The digestion process in amoeba is a simple process while in human beings it is a complex process. The process of ingestion and egestion are also quite different. Amoeba engulfs its food by surrounding the food particle with its pseudopodia. The undigested food is expelled out by the vacuole. While in human beings, the food (which is complex substance) is taken inside the mouth and undergoes a complex process of digestion and absorption in the digestive system. Finally the undigested food is expelled in the form of faeces.
