No they do not. They "eat" through a process known as phagocytosis.
Phagocytosis which literally means "cell eating" is the process by which cells ingest bacteria and other large foreign particles.
by phagocytosis
Phagocytosis
Eat - phagocytosis Drink - pinocytosis But these are special cases, inreality most cells rely on diffusion and active transport to get substances across the cell membrane.
Lysosomes in white blood cells that eat bacteria would store the waste of the bacteria until it could be removed from the body. This is part of the immune system.
they "engulf" the bacteria
pino- also means drink. If you use this meaning, pinocytosis would translate to drinking process of the cell. This is a good name for the process it describes because it involves taking liquids into the cell by means of endocytosis. Phagocytosis translates to eating process of the cell. Phagocytosis is a good name for the process it describes because the process involves the cell taking in particles of food by means of endocytosis.
It eats the salt you eat
Amoeba surrounds completely its prey with ithe projections of the protoplast , that are called pseudopodia. and along with some water, it takes in the prey within its cell. The process is called phagocytosis.
Amoebas move using psuedopodia (which means "false feet") and feed by phagocytosis- by englufing solid food through their cell membrane by use of internal food vacuole. Pseudopods are used to find food
Two ways a cell can eat food is by one, endocytosis which is when non-dissolved materials or food enter through the cell membrane to the cell's cytoplasm. These non-dissolved materials come from the outside environment. This way also includes phagocytosis in which an cell use pseudopods to help bring in the non-dissolved materials from the outside environment in to the cytoplasm. The second way is what a plant cell use get it's food is by chloroplast ( part of a cell ) which makes food from carbon dioxide, sunlight, and water.
