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 .
In an amoeba, the water content is controlled by the contractile vacuole. It fills with water (entering the amoeba by osmosis) and then empites the water once it reaches a certain level. If water was not displaced by the contractile vacuole, then the amoeba would burst.

The contractile vacuole in amoeba is related to osmoregulation, which is the process of regulating the water and ion balance within the cell. It helps to expel excess water and waste products to prevent the cell from swelling or bursting.

Amoebas are single-celled organisms that belong to the Protista kingdom. They do not have specialized organ systems like higher-level organisms. Instead, their functions are carried out by different organelles within the cell.
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.
Pseudopods act as feet and help in movement.

Paramecium is the most specialized organism listed. Paramecium have specific structures such as cilia for movement and feeding, contractile vacuoles for osmoregulation, and trichocysts for defense. Horse, Amoeba, and Worm are more generalized organisms in comparison.
Amoeba proteus is a unicellular organism with a shapeless, constantly changing cell membrane called a cell cortex. It lacks a fixed shape but generally exhibits an irregular, amorphous appearance with pseudopods (or false feet) used for movement and feeding. The cell contains a nucleus, contractile vacuoles for osmoregulation, and food vacuoles for digestion.
They have an excretory function.They remove excess water from cells.
