What is the relationship between photosynthesis and respiration in plants
Gabriel Cooper
Updated on May 02, 2026
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 the relationship between the rate of respiration and photosynthetic rate in green plants?
At this point the consumption of oxygen by the plant due to cellular respiration is equal to the rate at which oxygen is produced by photosynthesis. The compensation point for light intensity varies according to the type of plant, but it is typically 40 to 60 W/m2 for sunlight.
What is the difference between respiration and photosynthesis?
Photosynthesis is when energy, carbon dioxide and water react to produce glucose and oxygen. It is an endothermic reaction (takes in more energy than it gives off). Respiration is the process of producing energy from glucose.
What is the relationship between photosynthesis and respiration quizlet?
What is the relationship between photosynthesis and cellular respiration? Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back. Photosynthesis releases oxygen into the atmosphere, and cellular respiration uses that oxygen to release energy from food.Why do plants need 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.
How are photosynthesis and cellular respiration similar and different?
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. … For example, both processes synthesize and use ATP, the energy currency.
Do you find any relation between plants and animals by their respiration and photosynthesis?
Plants on Earth use photosynthesis to produce the molecules necessary for animals to live. And animals use cellular respiration to produce the molecules necessary for plants to live.
How respiration happens in plants?
As with photosynthesis, plants get oxygen from the air through the stomata. Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called “aerobic respiration”. In plants, there are two types of respiration: dark respiration and photo respiration.What happens when photosynthesis and respiration are equal?
compensation point The point reached in a plant when the rate of photosynthesis is equal to the rate of respiration. This means that the carbon dioxide released from respiration is equivalent to that which is taken up during photosynthesis. The compensation point is reached as light intensity increases.
What happens if the rate of respiration is more than the rate of photosynthesis in plant?Answer : If the rate of respiration exceeds the rate of photosynthesis, the plant will be using more oxygen than it can produce. Thus, the plant will be starved of food supply and finally die of starvation.
Article first time published onWhat happens in both respiration and photosynthesis quizlet?
Photosynthesis uses carbon dioxide and water, produces glucose and oxygen, and takes place in chloroplasts. Cellular respiration uses glucose and oxygen, produces carbon dioxide, water, and ATP, takes place in mitochondria.
Why is respiration considered the opposite of photosynthesis?
Photosynthesis and cellular respiration are almost opposite because photosynthesis takes in CO2 and releases oxygen whereas cellular respiration takes in oxygen and releases CO2.
How is respiration the opposite of photosynthesis quizlet?
Cellular Respiration and Photosynthesis are almost opposite processes because photosynthesis removes carbon dioxide from the atmosphere while cellular respiration puts back carbon dioxide. … Photosynthesis uses carbon dioxide and has it’s waste product of oxygen (O2).
What are similarities between photosynthesis and respiration?
Both photosynthesis and respiration involve the conversion of energy from one form to another through a series of biochemical reactions. Both processes use and produce ATP in reactions that are carried out on membranes and are controlled by enzymes.
What are three differences between respiration and photosynthesis?
Basis of ComparisonPhotosynthesisRespirationReactantsCarbon dioxide, water, and light energyGlucose and oxygen
Do photosynthesis and cellular respiration occur at the same time in a plant?
While photosynthesis only occurs during the day in plants and algae, cellular respiration occurs both day and night. The two processes take place in different cellular organelles (the chloroplasts and mitochondria, respectively) and can occur simultaneously.
Why do plants need respiration?
Plants are no exception. They need to respire virtually all the time in order to supply their energy needs. They are not able to use the ATP generated in photosynthesis for these purposes. … However, moving sugars around the plant seems to require energy as dead phloem cells do not transport sugars.
Why do plants need ATP during respiration?
ATP is an important source of energy for biological processes. Energy is transferred from molecules such as glucose, to an intermediate energy source, ATP. ATP is a reservoir of potential chemical energy and acts as a common intermediate in metabolism, linking energy requiring and energy yielding reactions.
How is respiration in plants and respiration in animals different?
Plants do not breathe, they only respire through their leaves. Animals breathe air for cellular respiration. Carbon dioxide released during respiration is utilized by plants for the photosynthesis process. Carbon dioxide released during respiration is not utilized by animals; it is released outside the body.
What role do photosynthesis and cellular respiration have in an ecosystem?
photosynthesis and cellular respiration allow the carbon and oxygen that organisms consume and produce to be cycled through the ecosystem. They work together so that what is made from one process is used in the other. Without them the ecosystem would run out of carbon dioxide and oxygen, and everything would die.
What are the similarities between the respiration of plants and animals?
Respiration in plantsRespiration in animalsIn plants separate respiratory organs are absent. Respiration takes place through diffusion.In animals respiratory organs are generally present.They produce little heat as compared to animals.They produce more heat.
What is difference between respiration and breathing?
Breathing and respiration are two completely different but interrelated body processes which assist body organs to function properly. Breathing is the physical process of exchanging gases whilst respiration is a chemical process which takes place at a cellular level and produces energy.
What is photosynthesis in plants?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar. 5 – 8.
How does respiration occur in the leaves?
Respiration in leaves takes place through stomata that is present as tiny pores in the leaves of a plant. Oxygen gets diffused in stomata and reaches other cells of the leaves. The carbon dioxide produced in the process of respiration also gets diffused with stomata and moves out of the leaves.
Which of the following is correct for respiration in plants?
Answer : Exchange of gases in plants takes place through their leaves. They take in oxygen through their tiny pores in leaves and give out carbon dioxide to air. Respiration in plants occurs both during day and night, but they produce their food through photosynthesis only during daytime.
Which is faster photosynthesis or respiration?
The cell uses oxygen and glucose to create water, carbon dioxide, and energy. … Well, the rate of photosynthesis is usually faster than respiration, so a plant produces more oxygen than it needs for itself.
What happens if the rate of respiration is more than the rate of photosynthesis in a plant Brainly?
When respiration becomes more than photosynthesis, the plant becomes dry and exhaust as the biomolecules present in the plants break down to compensate the process of photosynthesis.
When photosynthesis is faster than the rate of respiration oxygen gas is?
What is this? During daytime, photosynthesis produces oxygen and glucose faster than respiration consumes it. Photosynthesis also uses carbon dioxide faster than respiration produces it. Oxygen surplus is released into the air and unused glucose stored in the plant for later use.
How are photosynthesis and cellular respiration dependent on each other quizlet?
How are photosynthesis and cellular respiration dependent on each other? Photosynthesis supplies the oxygen needed for cellular respiration. Also, cellular respiration then supplies the carbon dioxide needed for photosynthesis.
Which statement is true for both photosynthesis and cellular respiration?
Both photosynthesis and cellular respiration needs organelles to conduct their processes is true and all other statements are false.
In what way are photosynthesis and cellular respiration similar quizlet?
Photosynthesis and cellular respiration are similar because both reactions contain water, carbon dioxide, glucose, oxygen and energy. … Cellular respiration takes a glucose molecule and combines it with oxygen; the result is energy in the form of ATP, along with carbon dioxide and water as waste products.
