NEET BIOLOGY

Detailed explanation-1: -Muscle cells undergo contraction and relaxation to cause movement. Therefore, these cells require more energy as compared to skin cells. Thus, they have more number of mitochondria compared to skin cells.

Detailed explanation-2: -Muscle cells have more number of mitochondria than the other cells in the body.

Detailed explanation-3: -Due to their relatively high energy demand, muscle cells require a particularly high number of mitochondria compared to other cell types.

Detailed explanation-4: -Nearly all our cells have mitochondria, but cells with higher energy demands have more. For instance, a skin cell has just a few hundred, while the cell pictured here has about 5, 000.

Detailed explanation-5: -Some cells, such as human nerve and muscle cells, contain many more mitochondria than do other cells, such as skin cells.
