All the cells shown are part of the same organism. which can you infer to be
true?

o
all of the cells came from the same cell.
o
all of the cells are able to produce food molecules.
o
all of the cells have the exact same function.
o
all of the cells have the exact same structures.

The cell in the middle differs from its surrounding cells by having a double cell membrane hence the cells do not have the exact same structure and most likely do not come from the same cell. For cells to produce food molecules, I am not too sure but I feel that the question is referring to plant cells that are able to photosynthesize. Plant cells have a cell wall and a cell membrane hence is unlikely to be represented by most of the cells in this diagram. Thus by elimination, the answer could be having the same function

That is true tge cactus as a structural adaptation to its envirinment has it leaves reduced to spines. but this doesnt mean it cant produce food it produces food because of the presence of chlorophyll in its stem
