A moss cell is placed in culture with an unknown chemical substance.It is found that the cell appears able to "divide," because the cell is observed to grow and replicate its internal organelles and nuclei, but it does not form primary cell walls.It appears that the substance has affected the synthesis of the polysaccharides that compose the cell wall.Which organelle is possibly targeted by the unknown chemical?
A) Nucleus
B) Plasmodesmata
C) Mitochondrion
D) Golgi apparatus
E) Chloroplast

Question

Quizplus · Accepted Answer

The Golgi apparatus is responsible for synthesizing and modifying polysaccharides that make up the cell wall. Therefore, if the substance has affected the synthesis of these polysaccharides, then it is likely targeting the Golgi apparatus. The nucleus, plasmodesmata, mitochondrion, and chloroplasts are not directly involved in synthesizing the cell wall, so they are less likely to be targeted by the substance.
