Why Is It Possible For A Plant To Photosynthesize And Respire At The Same Time?

As mentioned a plant produces glucose as food for itself. … This is chemical energy that the plant can use during chemical reactions in cells that require energy. So not only do plants perform both photosynthesis and cellular respiration but as long as there is sunlight they can perform both at the same time.

Is it possible for a plant to be doing photosynthesis and respiration at the same time?

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 do both photosynthesis and 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 do plants obtain carbon dioxide for photosynthesis?

For photosynthesis green plants take carbon dioxide from the air. The carbon dioxide enters the leaves of the plant through the stomata present on their surface. Each stomatal pore is surrounded by a pair of guard cells. The opening and closing of the pores of stomata is controlled by the guard cells only.

Do plants only require photosynthesis for growth?

No plants cannot grow without photosynthesis. Photosynthesis is needed to make chemical products to make energy for the plant. The energy is then used to grow the plant. If a plant doesn’t have photosynthesis it doesn’t grow and will die.

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.

Why do plants need to respire?

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. Plants respire in the normal way using glycolysis Krebs cycle oxidative phosphorylation etc.

Which of the following occurs in both photosynthesis and respiration?

The answer is (a) chemiosmosis.

Where do respiration and cellular respiration takes place?

mitochondria
While most aerobic respiration (with oxygen) takes place in the cell’s mitochondria and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.Feb 12 2020

Which part of the plant takes in carbon dioxide from the air for photosynthesis answer?

stomata

For photosynthesis green plants take greenhouse gas from the air. The CO2 enters the leaves of the plant through the stomata present on their surface. Each stomatal pore is surrounded by a pair of guard cells. The opening and shutting of the pores of stomata is controlled by the guard cells only.

How do plants get CO2 from the air?

Plants absorb carbon dioxide through small openings called stomata that are on the surface of the leaf. If we zoom in on a plant leaf so close that we can see the cells we’ll find tiny openings called stomata. Stomata are holes made from spaces between special cells.

What is the 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.

Why do plants carry out photosynthesis?

Plants are autotrophs which means they produce their own food. They use the process of photosynthesis to transform water sunlight and carbon dioxide into oxygen and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.

Why do plants need carbon dioxide?

Photosynthesis acts as the lungs of our planet – plants use light and carbon dioxide (CO₂) to make the sugars they need to grow releasing oxygen in the process. … Since CO₂ is the main source of food for plants increasing levels of it directly stimulate the photosynthetic rate of most plants.

What is the similarity 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.

Why are photosynthesis and cellular respiration not opposite processes?

Cellular Respiration and Photosynthesis are almost opposite processes because photosynthesis removes carbon dioxide from the atmosphere while cellular respiration puts back carbon dioxide. Cellular respiration uses oxygen and has it’s waste product of carbon dioxide (CO2).

Do plants respire carbon dioxide?

A new study involving ANU and international collaborators has found plants release more carbon dioxide into the atmosphere through respiration than expected. Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration.

Why do animals respire more than plants?

Respiration rate is higher in animal than in plants because animals require more energy as compared to plants because animals move one place to another in search of food and water they are not stationary . Plants are stationary and requires less energy.

What happens during respiration in plants?

The plants get energy through the process of respiration in which glucose food breaks down in the presence of oxygen to form carbon dioxide and water with the release of energy. This energy is used by the plant for carrying out its various life processes.

How are the inputs and outputs of photosynthesis and respiration related to one another?

How are inputs and outputs of photosynthesis and respiration related to one another? The inputs of one are the outputs of the other. … Plants give off oxygen to animals through the process of photosynthesis and animals give off CO2 through the process of respiration.

Does cellular respiration occur in plants animals or both?

Cellular respiration occurs in the individual cells. … The cells in both plants and animals perform respiration. Carbon dioxide is also released into the atmosphere when fuels are burned such as in automobiles or factories. Plants take in carbon dioxide and release oxygen through their leaves.

Why does cellular respiration so important to the organism?

The Purpose Cellular Respiration

The purpose of cellular respiration is simple: it provides cells with the energy they need to function. If living things could not get the energy they need out of food it would be absolutely worthless. All living things would eventually die no matter the quality and amount of food.

Which part of the plant allows the plant to breathe in gas from the air?

stomata
Plants respire through plant pores called stomata. What is this? During respiration and photosynthesis gases go in and out of the plants through stomata using diffusion not breathing.Jul 29 2021

Do plant leaves absorb carbon dioxide?

Plant leaves have small openings called stomata all over their surfaces. The stomata open to absorb the carbon dioxide needed to perform photosynthesis. They also open to release the oxygen produced by this process. … Plant leaves are also able to absorb and release water through the stomata.

Which part of the plant take part in gaseous exchange from the air?

stomata

Leaves. The exchange of oxygen and carbon dioxide in the leaf (as well as the loss of water vapor in transpiration) occurs through pores called stomata (singular = stoma). Normally stomata open when the light strikes the leaf in the morning and close during the night.

Which process do both plants and animals do to add carbon to the atmosphere?

During the carbon cycle animals and plants add carbon dioxide to the atmosphere through cellular respiration and plants remove carbon dioxide through photosynthesis. The burning of fossil fuels releases more carbon dioxide into the atmosphere contributing to global warming.

How do plants breathe in carbon dioxide?

Typically stomata are open during the day and closed at night like some people’s mouths. Many other signals cause stomata to open and close. Open stomata allow carbon dioxide to enter the plant however water vapour can escape so regulation of stomata is crucial for maintaining plant water status.

Why do plants produce carbon dioxide and oxygen?

The green leaves of plants carry out both photosynthesis (in light) and respiration (all the time). Photosynthesis uses carbon dioxide to make sugar and produces oxygen as a byproduct. Respiration uses oxygen to release energy from stored sugar and produces carbon dioxide as a byproduct.

What is the relationship between photosynthesis and aerobic cellular respiration and why is this important to life on Earth?

While cellular respiration releases carbon dioxide into the environment photosynthesis pulls carbon dioxide out of the atmosphere. The exchange of carbon dioxide and oxygen during photosynthesis and cellular respiration worldwide helps to keep atmospheric oxygen and carbon dioxide at stable levels.

Why are cellular respiration and photosynthesis opposite processes 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 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 are chlorophyll and other pigments important in photosynthesis?

Chlorophyll and other pigments are important in photosynthesis because they help absorb the energy from light during the process. Pigments simply are substance that absorb light. And their colour comes from the lights that they reflect.

What energy is needed by photosynthesis organism during the process of photosynthesis?

During the process of photosynthesis cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell such as glucose.

Do plants carry out photosynthesis only during the day?

Complete answer:

Photosynthesis in plants occurs only during the day when there is the sunlight but plants respire throughout the day and night. … During photosynthesis plants use light energy to convert water and carbon dioxide into oxygen and energy-rich organic compounds.
