Amoebas are single celled organisms found in ponds, ditches and freshwater ponds. They feed mostly on microorganisms.
Amoebas move one place to another by expanding and contracting pseudopodia. When they sense food around, with the help of pseudopodia they surround, capture and engulf food.
Food vacuole and digestion:
The food gets trapped in the segment called food vacuole. Food vacuoles of amoeba are fluid filled membrane bound structures present inside the cytoplasm of the cell. The fluid inside vacuole contains several enzymes that digest the food
The digestive juices are ejected into the food vacuoles, where the food particles are digested and will be aborbed in the food vacuole, so that can be used for growth and maintenance. The undigested food will be expelled out of the vacuole.
