During phagocytosis of one cell to another, the larger cell engulfs the smaller cell by enclosing it in a part of its plasma mem
brane which then pinches off so the cell is then within the larger cell. Given this may have been the process that brought bacterial cells into the ancestors of eukaryotic cells as endosymbionts, what structural characteristics might be expected in mitochondria and chloroplasts?
Phagocytosis is the process by which cells ingest large particles, including other cells, by enclosing the particles in an extension of the cell membrane and budding off a new vesicle. During pinocytosis, cells take in molecules such as water from the extracellular fluid.
