Main source of energy in cells is by burning the glucose, fats and excess of amine acids, by a process called biological oxidation. In all these, we get organic molecules of lower and lower energy level and releasing energy step by step, witch is trapped in making by converting ADP into ATP and some part into heat energy. For example, there are almost 20 steps through witch we come down in breaking glucose into final products of oxidation. (C O 2 and H 2 O. )
Plants convert energy in a process known as photosynthesis.
This occurs in organelles called chloroplasts, which contain chlorophyll.
The absorption of light by chlorophyll allows for the creation of biochemical fuel and ATP by the plant cells.
Almost all cellular functions require the cell to have energy. Cells need energy to grow, move, and clean out bad bacteria
Depending on what type of cell it is the energy may be converted through cellular respiration or photosynthesis, from a unuseable form of energy to a useable form like ATP.
Cellular respiration is the process by which all organisms release energy stored in the bonds of glucose.

oxidation
The first step of the process is the digestion.
ATP [Adenosine Triphosphate ] is a energy giving universal molecule . It give energy to almost every biological process like Krebs cycle , photosynthesis ,Respiration etc .
That process is called as biological oxidation. Glucose is the best example of biological oxidation. Here the end products are same. They are water and carbon bi oxide. In the biological oxidation the energy is released in step wise fashion in multiple steps. In the chemical oxidation the energy is released in single step. The amount of energy is exactly same in both the processes. Chemical oxidation is like jumping from the top of the building. Biological oxidation is like coming down via steps. You come down at the same place. But you may end up in braking your legs in the process of jumping down. In biological oxidation, you do not end up in braking your legs.
Cellular respiration is the process that "withdraws" the energy.
Cellular respiration is the specific cellular process that breaks down food to make energy. Catabolism is the general process that breaks molecules down to release energy.
Mitochondria gets energy from glucose through the process of cellular respiration.
