Why do plants use both photosynthesis and cellular respiration?

Why do plants use both photosynthesis and cellular respiration?

Just like animals can’t live without cellular respiration, plants can’t live without cellular respiration, either. Photosynthesis and respiration in plants are complementary processes because photosynthesis is only one half of the process of getting energy for a plant. It’s how they make food, not how they consume it.

What is an example of photosynthesis and cellular respiration working together?

Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

How does the relationship between photosynthesis and cellular respiration show the conservation of mass and energy?

The AMOUNT of oxygen and carbon atoms released by photosynthesis are EXACTLY EQUAL to the atoms of these material contained in carbon-dioxide converted. In this way photosynthesis has conserved the mass or material, and in this way followed the law of conservation of mass.

Do plants do both photosynthesis and cellular respiration?

Both the photosynthesis and cellular respiration simultaneously undergo, but the photosynthesis is confined into the presence light only, while respiration is continuous process.

Do plants do cellular respiration at night?

Depending on the amount of sunlight, plants can give out or take in oxygen and carbon dioxide as follows​1​. Dark – Only respiration takes place. Oxygen is consumed while carbon dioxide is released in plant respiration at night. Dim sunlight – Photosynthesis rate equals respiration rate.

What are the similarities and differences of photosynthesis and cellular respiration?

The two processes are similar in that they both produce energy, albeit in two different forms. They are different in that photosynthesis assembles the glucose molecule, while cellular respiration takes it apart.

What are 3 differences between photosynthesis and cellular respiration?

Cellular respiration takes place in the mitochondria of cells. While photosynthesis requires energy and produces food, cellular respiration breaks down food and releases energy. Plants perform both photosynthesis and respiration, while animals can only perform respiration.

What is the unique relationship between photosynthesis and cellular respiration?

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

What is an important similarity between photosynthesis and cellular respiration?

Do plants need cellular respiration to survive?

Plants need oxygen because plants are made living cells which need to perform cellular respiration to get the energy they need to function. Admittedly, needing to perform cellular respiration alone does not mean that consuming oxygen is required – many (micro)organisms use fermentation or anaerobic respiration.

Do plant cells do cellular respiration?

Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP. This process releases carbon dioxide and water as waste products. Plants have mitochondria and can perform cellular respiration.

How does respiration and photosynthesis work together in plants?

Photosynthesis and respiration work together in many ways. They both have to exist in symbiosis. But because of photosynthesis and cellular respiration, energy from the sun is converted into a ATP that fuels the work of plant cells.

How are carbon dioxide and water used in photosynthesis?

Photosynthesis. Respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy. This energy is used to fuel growth and all of the normal cellular functions. Carbon dioxide and water are formed as by-products of respiration (Figure 4).

What is the relationship between photosynthesis and energy?

The relationship between photosynthesis and cellular respiration is such that the products of one system are the reactants of the other. Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen.

What is the relation ship between cellular respiration and photosynthesis?

The relationship between photosynthesis and cellular respiration is such that the products of one system are the reactants of the other. Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water.
