When waste is created, a vacuole will capture the waste and take it to the cell membrane. Here the plasma membrane of the vacuole merges with the plasma membrane of the cell. Contractions occur and the waste is spewed back out into the interstitual fluidl.

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	Endocytosis
B	Exocytosis

Explanation:

Detailed explanation-1: -In exocytosis, waste material is enveloped in a membrane and fuses with the interior of the plasma membrane. This fusion opens the membranous envelope on the exterior of the cell and the waste material is expelled into the extracellular space.

Detailed explanation-2: -Vacuoles are broken down by the cell, with the particles used as food or dispatched in some other way. Pinocytosis is a similar process on a smaller scale. The cell expels waste and other particles through the reverse process, exocytosis.

Detailed explanation-3: -The steps of exocytosis The vesicle travels to the cell membrane. The vesicle fuses to the plasma membrane, during which the two bilayers merge. The vesicle’s contents are released into the extracellular space.

Detailed explanation-4: -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 vacuole.
