exocytosis
Amoebas eliminate waste through a process called exocytosis, where waste materials are packaged into vesicles and expelled from the cell. These vesicles fuse with the cell membrane, releasing the waste outside the cell.
In unicellular organisms, waste removal typically occurs through simple diffusion, where metabolic byproducts passively exit the cell across the plasma membrane. In contrast, multicellular organisms have specialized systems, such as the excretory and circulatory systems, to transport and eliminate waste products efficiently from various tissues. This complexity allows multicellular organisms to manage waste removal across different cells and organs, ensuring that all cells remain in a stable environment. Overall, the process in multicellular organisms is more intricate and coordinated compared to the direct and straightforward method used by unicellular organisms.
Unicellular organisms obtain oxygen and dissolved substances through diffusion. This process allows molecules to passively move across the cell membrane from an area of higher concentration to an area of lower concentration. This is how unicellular organisms can intake essential nutrients and eliminate waste products.
The organelle responsible for expelling ammonia in amoeba is called the contractile vacuole. This structure helps regulate osmotic pressure by collecting excess water and waste products, including ammonia, and expelling them from the cell. The contractile vacuole contracts to push out the waste, maintaining the internal environment of the amoeba. This process is crucial for the survival of the organism in its aquatic environment.
In unicellular organisms, transportation occurs primarily through diffusion and osmosis. Nutrients, gases, and waste products move across the cell membrane directly into or out of the cell due to concentration gradients. Some unicellular organisms also utilize specialized structures, like contractile vacuoles, to help regulate the internal environment and expel excess water. Additionally, some may use cilia or flagella for movement, which can aid in the transportation of substances in their environment.
Single-celled organisms get rid of waste by first creating pockets of air around the waste material. Then they eject these air pockets, waste and all.
Unicellular organisms typically range in size from a few micrometers to a few hundred micrometers, with some exceptions reaching up to one millimeter. These sizes are optimal for efficient nutrient uptake and waste removal due to their high surface area to volume ratio, allowing for rapid exchange with the environment.
Unicellular organisms get rid of waste through the process of exocytosis, where waste products are expelled from the cell through the cell membrane. Some unicellular organisms can also break down waste products within specialized compartments called vacuoles before expelling them.
Cells do the same, or very similar things, whether they are part of a unicellular organism or a multicellular organism; they have a metabolism, they consume nutrients and oxygen, they have waste products, etc.

Amoebas eliminate waste through a process called exocytosis. They form vesicles containing waste materials and then expel these vesicles from the cell through the cell membrane. This helps keep the internal environment of the amoeba clean and functioning properly.

No, not all unicellular organisms have vacuoles. Vacuoles are membrane-bound organelles found in some eukaryotic cells that store water, nutrients, and waste products. While many unicellular organisms have vacuoles, there are some that may not possess this organelle.
They eat several unicellular organisms such as lean meats, celery bits, sea weed, human waste and hairs.
