Food serves as a source of raw materials from which the cells of the body can synthesize new molecules, provides living things with the chemical building blocks they need to grow and reproduce, and as a source of energy.
Oxygen is used to break down glucose in the process of cellular respiration.
So yes, cells need food and oxygen.
However, plant cells make their "food" (glucose) by the use of photosynthesis.

∙ 15y agoFirstly, energy can't be created or destroyed, instead I think you mean release energy.
A cell does need oxygen for aerobic respiration which eventually produces ATP, which is used in metabolic reactions to release energy as it forms ADP and Pi.

Do plants need oxygen?
Yes and lots of it. The oxygen provides the plants with energy to produce clorophyl which will incduce photocinecus
How does an understanding of the process of cellular respiration support the theory that the cell is the basic functional unit of life?
Each individual cell needs energy and oxygen to survive, just as living things do. Cellular respiration explains why living organisms need oxygen and energy, and exactly where those resources go.
Plants need oxygen to release the energy in the food that they make?
plant need oxygen to release the energy in the food that they make because the oxygen molecule react with hydogen to produce water in the light reaction which takes place inside the leave
What organelles does mitochondria need to survive?
organelles need many things to survive but they mostly need energy, water, mineral's, and vitamins
What is the process called that glucose is needed for by every cell in the body?
The glucose and oxygen react together in the cells to produce carbon dioxide and water. The reaction is called aerobic respiration because oxygen from the air is needed for it to work. (Energy is released in the reaction.)
What does a cell need to produce energy?
Oxygen
What does a cell need for cell respiration to occur?
aerobic respiration needs oxygen to generate energy, occasionally anaerobic respiration can occur which is when an organism can produce energy without using oxygen. Most cells need oxygen to respire. The simple reaction is: glucose + oxygen = energy + waste products (carbon dioxide + water)
In biology what is cell respiration?
Cell respiration is the way a cell "breathes" and produces energy. There are two kinds of cell respiration. First one is called "aerobic", meaning the cell uses oxygen, the other one called "anaerobic" means the cell doesnÇ_t need oxygen to produce energy.
Why do you need to breathe in oxygen?
oxygen is needed to produce energy from food
Does metabolism need oxygen to work?
Yes, oxygen is necessary when burning nutrients to produce energy.
Why do multicellular organisms need to use more energy?
A multicellular organism can not rely on glycolysis alone for energy because glycolysis is just one step in respiration. Glycolysis alone does not produce the amount of oxygen that a multicellular organism needs.
Does respiration use oxygen?
If by respiration you mean cell respiration, then yes oxygen is consumed in the process of cell respiration. As a matter of fact, oxygen is the last electron acceptor in the electron transport chain, the last stage of cell respiration. In cell respiration, you produce ATP, which is essentially used by your body to get energy. That is why you need oxygen! !!
Do plants produce food without any oxygen?
They dont need oxygen to produce food (Glucose), they use carbon dioxide to produce this but they do need oxygen to respire and get energy from the food that they produuced. The process by which food is produced is called photosynthesis.
Do plants need oxygen?
Yes and lots of it. The oxygen provides the plants with energy to produce clorophyl which will incduce photocinecus
Why does respiration happens in every cell?
Every cell need to respire in order to produce the energy it needs
What is the name for the release of energy from food?
all of your cell need oxygen , so they can release energy from glucose by respiration
Why respiration takes place in every cell?
Every cell need to respire in order to produce the energy it needs
