energy
Cells in the body do not need to carry out every function independently. They depend on other cells and systems to support their activities. Additionally, not all cells in the body need to divide constantly, with some cells being quiescent or terminally differentiated.
Muscle cells require a lot of energy to contract and perform their functions, so they need a high concentration of mitochondria to generate ATP through aerobic respiration. Mitochondria produce the majority of the cell's energy supply in the form of ATP, making them essential for muscle function. Additionally, the presence of abundant mitochondria helps to meet the high energy demands of muscle cells during exercise and movement.
The levels of organization of life are cells, tissues, organs, organ systems, organisms, populations, communities, and ecosystems. For example, cells are the basic unit of life (e.g., red blood cells, nerve cells), while tissues are groups of cells working together (e.g., muscle tissue, nerve tissue). Organs are structures composed of tissues with specific functions (e.g., heart, lungs), while organ systems are groups of organs working together to perform a particular function (e.g., digestive system, respiratory system).
One key difference is that one-celled organisms, like bacteria or protists, are complete living entities on their own, whereas cells in an organ are part of a multicellular organism and depend on other cells for survival. Cells in an organ are typically specialized for specific functions to contribute to the overall function of the organ, while one-celled organisms must perform all necessary functions independently.

Because the cells themselves need energy to perform their specific function, and to reproduce!
Muscle cells, especially those found in the heart and skeletal muscles, require a significant amount of energy to perform their functions. Therefore, they would need to have more mitochondria to meet their high energy demands.
food is used up by all the cells in the body as all the cells need energy to perform their functions
Cells in the body do not need to carry out every function independently. They depend on other cells and systems to support their activities. Additionally, not all cells in the body need to divide constantly, with some cells being quiescent or terminally differentiated.
Passive transport cells do not need to expend ATP to perform. These cells rely on the natural movement of particles along a concentration gradient to enter or leave the cell, without the need for additional energy input.
Cells that need more respiration typically include those that are highly active and require lots of energy. Examples of these cells include: Cells in muscle tissue Brain cells Cells in the heart Cells in the lining of the small intestineThese cells require more respiration in order to produce the energy they need to perform their intended functions.
