Question

look at the data in the table to the right. then, answer the question that follows. based on the data in the table, what conclusion can you draw about the energy needs of different cells? all cells need the same amount of energy. skin cells use more energy than muscle cells. cells that need more energy, like muscle cells, have more mitochondria. cells that have more mitochondria are larger than other types of cells.

Explanation:

Mitochondria are the energy - producing organelles (the "powerhouses") of the cell. The table shows that muscle and liver cells (which have higher energy demands) have a greater number of mitochondria (more than 2000) compared to skin cells (which have lower energy needs, with only 200 mitochondria). This supports the conclusion that cells with higher energy requirements have more mitochondria. Option A is incorrect because the data shows different cell types have different numbers of mitochondria (implying different energy needs). Option B is wrong as skin cells have fewer mitochondria (less energy) than muscle cells. Option D is not supported by the data; the table does not provide any information about cell size in relation to the number of mitochondria.

Answer:

C. Cells that need more energy, like muscle cells, have more mitochondria.
