Nutrition in Unicellular Organisms Class 10 Science In unicellular organisms, the entire surface consumes the food. Amoeba Amoeba is a single-celled organism that consumes food using transient finger-like protrusions of the cell that fuse over the food particle to form a food vacuole, where the food is then broken down and diffused into the cytoplasm. The unabsorbed food is transported to the cell surface where it is expelled. Paramecium Another unicellular organism, Paramecium, has a specific location in the body where it may ingest nourishment. The movement of cilia, a structure that resembles hair and is found in the body of a paramecium, transports food to the area. Nutrition in Amoeba: Amoeba has holozoic nutrition. Thus, solid food particles are ingested which react with enzymes and are digested. It is an omnivore. 1. The unicellular species known as the amoeba exhibits the Holozoic style of nourishment. Membrane from amoeba cells continues to protrude into pseudopodia. Amoeba f
