amoeba is a microscopic single celled organism found in pond water .Amoeba has a cell membrane,a rounded,dense nucleus and many small bubble like vacuoles in its cytoplasm. Amoeba constantly changes its shape and position. It pushes out one,or more finger like projection s,called pseudopodia or false feet for movement and capture of food.
Amoeba feeds on some microscopic organisms.When it senses food,it pushes out pseudopodia around the food particle and engulfs it.The food becomes trapped in a food. vacuole.
Digestive juices are secreted into the food vacuole .They act on the food and break it down into simpler substances .Gradually the digestive food is absorbed. The absorbed substance are used for growth,maintenance and multiplication.The undigested residue of the food is expelled outside by the vacuole.
