Amoeba, a single-celled organism, is a type of protozoan that is capable of obtaining its nutrition through a process called phagocytosis. This process involves the engulfing of food particles and their subsequent digestion and absorption.
Digestion in Amoeba
Digestion in amoeba occurs within a food vacuole, which is formed as a result of phagocytosis. The food vacuole is surrounded by a membrane that contains digestive enzymes, which break down the food particles into smaller molecules. The end products of digestion are then absorbed into the cytoplasm of the amoeba.
Absorption in Amoeba
Absorption in amoeba occurs through the cytoplasmic membrane, which allows the end products of digestion to enter the cytoplasm. The absorbed molecules are then utilized by the amoeba for energy and growth.
In conclusion, digestion and absorption are essential processes in the nutrition of amoeba. Through phagocytosis, amoeba is able to obtain its nutrition and sustain its growth and survival. Understanding these processes helps us gain a deeper understanding of the nutritional needs of single-celled organisms and how they obtain their sustenance.
