Question

Cells are specialized to do certain jobs. For instance, muscle cells are in constant motion and require a lot of energy to work. Muscle cells contain more of which organelle?

A.
mitochondria because they produce energy for the cell

B.
chloroplasts because they produce energy for the cell

C.
cell wall because it produces energy for the cell

D.
cell membrane because it produces energy for the cell

Answer 1

A. mitochondria because they produce energy for the cell

Mitochondria generate ATP by cellular respiration, supplying the high energy needs of active cells like muscle cells. Chloroplasts do photosynthesis in plants; cell wall and cell membrane do not produce energy.
