Long Answer Questions
Explain the process of nutrition in Amoeba.
Answers
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 .
Answer:
The made of nutrition in amoeba is holozoic . The various step involved in the process of nutrition are ingestion. Amoeba ingests food with the helps of its finger - like expension , called pseudopodia........assimilation : Amoeba cell obtains energy from the absorbed food through respiration.
