Although hospice and palliative care share the same principles of providing comfort and support for patients, palliative care is available throughout a patientâs experience with cancer, whereas hospice is offered only toward the end of life.
The process used by some protists to actively ingest food particles is called Phagocytosis.ther protists like fungus grow  above their food source to get nutrients. Some protists engulf  bacteria and digest them internally, by extending their cell  membrane and forming a vacuole around the bacteria.
Phagocytosis, process by which certain living cells called phagocytes ingest or engulf other cells or particles. The phagocyte may be a free-living one-celled organism, such as an amoeba, or one of the body cells, such as a white blood cell. In some forms of animal life, such as amoebas and sponges, phagocytosis is a means of feeding. In higher animals phagocytosis is chiefly a defensive reaction against infection and invasion of the body by foreign substances (antigens). The process by which cells engulf solid matter is called phagocytosis. There are four essential steps in phagocytosis: (1) the plasma membrane entraps the food particle, (2) a vacuole forms within the cell to contain the food particle, (3) lysosomes fuse with the food vacuole, and (4) enzymes of the lysosomes digest the food particle.
