Question

how do Amoeba and Hydra get mission is there any difference in the way to digest food

Answer 1

hey friend,


here is ur answer,



Amoeba:



Amoeba is a microphagous feeder,it feeds upon small aquatic organisms like bacteria,protozons,small substances like algae and small dirt particles........ It engulfs the food particles along with water drops with the help of psendopdia and form food vacuole, this is called Indestion. Now lysosomes attach with the membrane of food vacuole and secrete different types of enzymes like proteases..............amylases and lipses to decompose proteins, starch and lipids respectively............
In this way the food is digested in the food vacuole..............






Hydra:



Hydra is a aquatic animal with vase shaped digestive cavity..............it feeds upon small aquatic animals like crustaceans,small annelids and insect larvae........ The glandular cells of inner body layer called gastroderm secrete enzymes which digest food partially in the cavity called Extra cellular Digestion. Now gastodermal flagellate cells and body contractions mix up the food with enzymes, so that food is broken into fine particles, which are engulfed through phagocytic action of inner layer cells, where intracellular digestion is completed in the digestive vacuoles.
Now this digested food is diffused to outer layer cells called epidermis. The undigested food is expelled out from mouth as Hydra has no anus.
This is called Sac-like Digestive System...........
