What Type of Nutrition is Shown in Amoeba?

Amoeba is a single-celled organism that belongs to the phylum Protozoa. It is a type of protist and exhibits holozoic nutrition, which means it obtains its food by ingesting other organisms or organic matter.

Amoeba feeds by extending its pseudopodia, which are temporary arm-like projections of its cell membrane. These pseudopodia surround and engulf prey organisms or particles of organic matter, forming a food vacuole. The food vacuole then fuses with a lysosome, a specialized organelle that contains digestive enzymes. The enzymes break down the food particles into simpler molecules such as amino acids, sugars, and fats, which are then absorbed into the cytoplasm of the amoeba and used for energy and growth.

In summary, amoeba exhibits holozoic nutrition, which involves the ingestion and digestion of other organisms or organic matter. This is a common type of nutrition among protists and other unicellular organisms.
