The answer is a the nervous system
The nervous system is connected to your brain and controls each and every action in your body.
The two main processes by which plant cells absorb, release, and use
energy are photosynthesis and respiration. The
process of photosynthesis is present in the chloroplasts of a pant cell.
Photosynthesis uses the sun’s rays in the form of electromagnetic energy to
convert it into chemical energy to be used for the plants. It needs proteins
that are present in the plants to perform a series of necessary conversions.
Moreover, the energy from the sun is the main catalyst to convert the
carbohydrates in the plant into simpler sugars. And then a series of complex
reaction takes place that their end product is oxygen. The oxygen produced is
the cellular respiration.
In order for cells to become whole organisms, they must divide and differentiate. Cells divide all the time. That means that just one cell, a fertilized egg, is able to become the trillions of cells that make up your body, just by dividing. Those trillions of cells are not all the same though.
Just a little while after you started out as a fertilized egg, your cells started performing specific tasks, even started to look different because of that. Differentiation means that one cell performs a different function than another cell, depending on where it is in your body.
