During infection with Listeria, an intracellular bacterium, APCs will present antigen on MHC II molecules and triggers a phagocytic property by stimulating the release of macrophages.
What is the role of macrophages in Phagosomes?
Phagosome maturation was formerly regarded to be a very simple notion that described how much phagosomes had united with lysosomes.
- Unfortunately, this assumption is no longer valid because phagosomes are now known to interact with a variety of intracellular organelles during their maturation process.
- Proteins, such as the NADPH oxidase complex that creates the superoxide burst, may be seen being assembled on the phagocytic cup even before they are fully formed.
- When the phagosome closes and the maturation process begins, it becomes increasingly acidic and hydrolytically active, and it transiently fuses with the recycling endosomal system, the secretory system, including secretory lysosomes, multi-vesicular bodies such as the MHC class II (MIIC) compartment, and even the endoplasmic reticulum.

Answer:
b. The rigid cell walls limit how far plant cells can expand and exert a back pressure to limit further water uptake.
Explanation:
Plant cells have a rigid cell wall made of cellulose. Animal cells lack a cell wall.
When the plant cells are placed in a hypotonic solution, water enters into the cells and the cells expand. However, after a certain limit, the cell wall exerts wall pressure on the contents of the cell and does not allow it to take more water in. The wall pressure from the cell wall of plant cells protects them against bursting when placed in a hypotonic solution.
Animal cells burst out due to intake of water by osmosis when placed in a hypotonic solution. They do not have a cell wall to protect them from bursting.
