Vacuole
Vacuoles are membrane-bound sacs within the cytoplasm of a cell that function in several different ways. In mature plant cells, vacuoles tend to be very large and are extremely important in providing… More »
Such vesicles are called food vacuoles. Digested food particles pinch away from the food vacuoles into tiny vesicles. These vesicles provide a much larger surface area to facilitate the absorption of nutrients by the rest of the cell.

1. In Amoeba new food vacuoles which contain chilomonads or colpidia decrease greatly in size and the organisms in them die soon after they have decreased to minimum; then the size increases rapidly and digestion begins, after which the size decreases very gradually.

Each T. pyriformis cell concentrates the spores and crystals in its food vacuoles, thus delivering them to mosquito larvae, which rapidly die. Vacuoles containing undigested material are later excreted from the cells.
