Question

write a short note on nutrition in amoeba

Answer 1

Nutrition in amoeba is holozoic. Thus, solid food particles are ingested which are then acted upon by enzymes and digested. It is an omnivore, feeding on both plants and animals. Its diet includes bacteria, microscopic plants like the diatoms, minute algae, microscopic animals like other protozoa, nematodes and even dead organic matter.

Since it is a unicellular organism, amoeba does not have any specialised structure or organ for the process of nutrition. It takes place through the general body surface with the help of pseudopodia.

Answer 2

Nutrition in amoeba...
The various steps involved..
1.) Ingestion.. : amoeba ingests food with the help of finger like extension called pseudopia. When the food particles approaches ameoba it forms psuedopodia around it.... N forms food vacuole inside the amoeba..
2.) Digestion : various enzymes from the cytoplasm enter into the food vacuole n break down into simple molecules.
3.) Absorption : the simple soluble food is adsorbed by cytoplasm through the process of simple diffusion.
4.) Assimilation : amoeba call obtain energy from the food through respiration this energy utilised by amoeba for iths growth n repair..
5.) Egestion : when a considerable amount of undigested food gets collected inside amoeba... Its call membrane ruptures n throws out the undigested food..

Hope its helpzz :)
