Regarding this, why do cells break down sugars?

In a plant cell, chloroplast makes sugar during the process of photosynthesis converting light energy into chemical energy stored in glucose. In mitochondria, through the process of cellular respiration breaks down sugar into energy that plant cells can use to live and grow.

Beside above, why do cells need glucose? Most of the cells in your body use glucose along with amino acids (the building blocks of protein) and fats for energy, but it's the main source of fuel for your brain. After your body has used the energy it needs, the leftover glucose is stored in little bundles called glycogen in the liver and muscles.

Furthermore, what releases energy from sugars?

In cells use oxygen to release energy stored in sugars such as glucose. In fact, most of the energy used by the cells in your body is provided by cellular respiration. Just as photosynthesis occurs in organelles called chloroplasts, cellular respiration takes place in organelles called mitochondria.

How does the body use sugar?

Sugars are a source of energy for the body. Simple sugars then travel through the blood stream to body cells. There they provide energy and help form proteins, or are stored for future use. The brain and red blood cells can only use glucose for energy.
