They get the materials by the food and air they eat and breathe in to receive the glucose and oxygen. This is also why athletes need to have a sports scientist to advice them on food and drink to improve their performance.

Cells get the materials they need for respiration through the process of diffusion, where gases like oxygen and carbon dioxide move in and out of the cell membrane. Oxygen is taken in from the environment and transported by the circulatory system to the cells, while carbon dioxide is produced as a byproduct of cellular respiration and diffuses out of the cells.
the respiration reactants are carried in the blood stream by red blood cells which exchange respiratory reactants with cells through diffusion

Human cells get most of the energy they need from the process of aerobic cellular respiration which occurs in the mitochondria. Aerobic cellular respiration produces about 34 molecules of ATP.
The process that requires oxygen to release energy in cells is called cellular respiration. During cellular respiration, glucose is broken down in the presence of oxygen to produce ATP, which is the main energy source for cells.
All cells obtain energy from cellular respiration. Some undergo anaerobic respiration and some undergo aerobic respiration.
Chloroplasts are very important.They are responsible for photosynthesis.Mitochondria are important for respiration.
