MICROANATOMY

Detailed explanation-1: -Muscles cells contain a large number of mitochondria because muscle tissues require a large amount of energy for movement and especially during exercise. Since ATP is produced by mitochondria, muscles cells have a large number of mitochondria to fulfill the energy requirements.

Detailed explanation-2: -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-3: -Answer and Explanation: Muscle cells require large amounts of energy in order to function properly. Muscle cells contain more mitochondria within their cells, and these mitochondria produce more ATP by consuming energy from the foods we eat. On the other hand, fat cells do not require as much energy to function.
