name the glands associated with human digestion and describe digestion in amoeba
Answers
Answer:
The glands which secrete digestive juices for the digestion of food are called associated glands. They are:- salivary glands, gastric glands, liver, pancreas etc.
Amoeba is a unicellular organism. It undergoes intracellular digestion. The mode of nutrition in Amoeba is holozoic.
The process of obtaining food by Amoeba is called phagocytosis.
Ingestion: When a food particle is near the Amoeba, it forms temporary finger-like projections called pseudopodia around the food particle and engulfs it.
Digestion: The food is digested in the food vacuole with the help of enzymes.
Absorption: It is then absorbed in the cytoplasm of the Amoeba by diffusion.
Assimilation: The absorbed food provides energy and a part of nutrition is used for growth.
Egestion: The undigested and the waste food particles are thrown out.
