Answer»

◇Amoeba is a unicellular , omnivore organism that does not possess specialised organ for the process of NUTRITION .

◇The mode of nutrition in Amoeba is HOLOZOIC and takes place with the help of PSEUDOPODIA ( finger like structure ) .

◇It engulfs food when it comes in contact with its cell surface by ingestion .

◇Pseudopodia fuses over food particle to form food vacuole .

◇Digestion in Ameoba is INTRACELLULAR in nature. Inside the food vacuole, complex food breaks into small soluble molecules , This process is called ABSORPTION .

◇The absorbed food is further ASSIMILATED by Amoeba to DERIVE energy for growth.

◇ The undigested food material is removed by the cell membrane, which ruptures suddenly at any place and eliminates out the undigested food.

◇The process of throwing out undigested food is called EGESTION .
