Question

Once solid material is phagocytized and taken into a vacuole, which of the following statements best describes what happens?

1) A ribosome enters the vacuole and uses the amino acids in the "invader" to form new protein.
2) A lysosome combines with the vacuole and digests the enclosed solid material.
3) The vacuole remains separated from the cytoplasm and the solid material persists unchanged.
4) Nitrogen enters the vacuole and "burns" the enclosed solid material.

Answer 1

A lysosome fuses with the phagocytized material's vacuole to digest it with enzymes and acids, and then the cell excretes the debris.

Step-by-step explanation:

Once solid material is phagocytized and taken into a vacuole, the best description of what happens is option 2) A lysosome combines with the vacuole and digests the enclosed solid material. During phagocytosis, the solid material is engulfed by the cell membrane and forms a phagosome. The phagosome then fuses with a lysosome, forming a phagolysosome. Digestive enzymes and acids from the lysosome break down and digest the enclosed solid material Once a solid material is phagocytized and taken into a vacuole, the correct statement that best describes what happens next is that a lysosome combines with the vacuole and digests the enclosed solid material.

The process starts with the solid material being engulfed by a portion of the plasma membrane to form a vesicle known as a phagosome. This phagosome then fuses with a lysosome, creating a phagolysosome where digestive enzymes and acids from the lysosome break down the solid material. After the pathogen is digested, the soluble debris is excreted from the cell through exocytosis.
