Explain the feeding and digestion
Explain the feeding and digestion in amoeba?
Amoeba is an unicellular, meaning single celled, microscopic, pond organism. Thought it is unicellular it functions all the essential functions of life, for example engulfing and digesting food, excretion etc.
You might be wondering How does it do it?
Let me explain but let’s learn about it’s structure first.
Amoeba has cell membrane, a rounded, dense nucleus and many small bubble like vacuoles in cytoplasm.
Amoeba keeps changing it’s position and shapes with the help of pseudopodia, a finger like projection on the surface of amoeba. It is also called false feet as it helps in movement of amoeba from one place to another.
Amoeba also uses pseudopodia to capture the food, for example when it senses the food, it pushes out pseudopodia surrounding the food particle and engulf it, so the food becomes trapped in a food vacuoles. Once trapped, digestive juices are secreted in to the food vacuoles to break it down in to simpler substances. which gradually gets absorbs in to amoeba. The absorbed food is used for growth, multiplication and maintenance of amoeba where as undigested residue of food is expelled out side by the vacuoles.
Amoebae move and feed by using pseudopods, which are bulges of cytoplasm formed by the coordinated action of actin microfilaments pushing out the plasma membrane that surrounds the cell. Groups of amoebae are distinguished by the appearance and internal structure of their pseudopods.
