12. Cells contain specialized structures called organelles that have specific functions that enable the cell to carry out life processes. Organelles work together to perform all the functions of the cell. Which of the following choices is
the best example of how the cell membrane and mitochondria might work together to make energy in a particular
cell?
a. In animal cells, the cell membrane allows materials in and out of the cell, while the mitochondria uses nutrients
to make energy (ATP) for the cell.
b. In animal cells, the mitochondria allows materials in and out of the cell, while the cell membrane uses nutrients
to make energy (ATP) for the cell.
c. In a plant cell, the cell wall allows materials in and out of the cell, while the mitochondria makes food for the cell
by photosynthesis.
d. In a plant cell, the mitochondria allows materials in and out of the cell, while the cell wall makes food for the cell
by photosynthesis.
