Amoeba is a protozoan animal that is unicellular microscopic and found in fresh and marine water. It is also a endoparasite. In amoeba only asexual reproduction takes place and is of three types. 1 Binary fission: takes place in favourable conditions( when enough food and adequate temprature is avialable) just like mitosis completed in half an hour. During binarry fission amoeba stops feeding pseudopodia contract, but not dissapear. Contractile vacoule goes to one daughter cell and in second new c.v. is formed. Cytoplasm content of daugher amoeba just after division is near about equal to parent amoeba. 2 By sporulation: not found in amoeba proteus but found in other species of amoeb. Takes place in unfavourable conditions. The cell form 500-600 chromatin granules which undergo sporulation in favourable conditions and 250-300 spores are relased which become amoeba. 3 By encystment:takes place under unfavourable conditions, about 500-600 amoeba are formed. RESPIRATION: amoeba is aerobic. Respiration system is absent. Respiration takes place by diffusion through general body surface. NUTRITION: It is holozoic, ingest food by phagocytosis Digestion is intracellular, takes place in food vacoule. Digestive enzyme released from lysosome. Trypsin and amylase are also found. EXCERETION: amoeba is ammonotelic but dicarbonyl urea crystals are also found. Exceretion takes place through general body surface.
Forams are single-celled organisms with shells made of calcium carbonate, while amoebas are single-celled organisms without a shell. Forams are primarily marine and have pseudopods for movement and feeding, whereas amoebas are found in various environments and also use pseudopods for movement and feeding.
an amoeba is 0.5 mm as big as a grain of salt
The amoebas are in the protista kingdom.
Amoebas reproduce asexually

Amoebas live because god made them.
The amoebas are in the protista kingdom.
Amoebas reproduce asexually
Amoebas live in the water with frogs. The relationship between amoebas and frog intestines, is that certain amoebas can be found feeding off of the intestines of the frog.
