Want this question answered?
Amoeba are not usually found in any organ unless there is an infection like amoebic dysentery. Amoeba are unicellular organisms that may cause infection in humans and animals.
it does not have any function
Amoeba are not photosynthetic. They do not have chloroplasts
Amoeba possess a contractile vacuole for excretion and osmoregulation . Undigested food is excreted by exocytosis . Some wastes wastes, and CO2 are excreted through the plasma membrane by diffusion .

Yes
When single cell freshwater organism is transferred in salt water it will shrink. For e.x. As in case of amoeba if fresh water amoeba is kept in salt water it contractile vacuole will disappear and this phenomena is called osmoregulation.
They use it to engulf or surround their food

Pseudopods act as feet and help in movement.
a granular inner mass called the endoplasm. The endoplasm contains the cell nucleus, which controls the amoeba's life processes. In most species, the endoplasm also contains a water bubble, called the contractile vacuole, that regulates the amoeba's water content. Within the endoplasm there are also bits of food enclosed in food vacuoles.
First i will like to introduce you to Osmoregulation Osmoregulation is the ability of an organism to maintain a constant osmotic pressure within the blood and tissue fluid. Different chemical activities in the body produce many by-products several of which are wastes. These waste products if allowed to accumulate will turn out to be toxic and affect the physiological activities of the body cells. These wastes have to be expelled out or it may eventually result in the death of the organism. Excretion is performed by the contractile vacuole.The content within the tissues of amoeba is hypotonic due to the salt concentration. so water turns to enter the cells rapidly than it is needed. The excess water if not expelled will eventually burst the cells. some of this excess water then diffuse into the contractile vacoule gradually and gradually until the vacuole becames turgid. The water is then expelled by diffusion out of the cells. By A.Smith
