No, plants do not always use cellular respiration. Like animals, plants use cellular respiration to release energy from glucose and other organic molecules that are formed from carbohydrates in photosynthesis.
However, this is not the only way that plants obtain energy. Depending on the species, certain plants might also use photophosphorylation, or light dependent electron transport, to generate energy. In photophosphorylation, energy is obtained by splitting water molecules and using the energy of the hydrogen radical to generate other molecules.
Plants can also capture energy from light directly through a process called light harvesting, in which plant cells absorb light energy and convert it into chemical energy that can be used for cellular processes.
Lastly, some plants might generate methane as an energy source, typically through a process called methanogenesis. This process occurs when microorganisms in the soil or roots of a plant break down organic matter, releasing methane as a byproduct.

Can all plants do photosynthesis yes or no?
Yes, all plants can do photosynthesis. Photosynthesis is a process used by plants and other organisms to convert light energy, usually from the Sun, into chemical energy that can be used to fuel the organisms’ activities.
Photosynthesis is vital for most life on Earth as it provides the main source of oxygen in the atmosphere and is the source of energy used by almost all organisms. All plants have the ability to convert carbon dioxide and water into glucose, which is then used to generate energy for the plant.
To do this, the plant uses sunlight, along with enzymes, to convert the energy into usable forms of energy, like carbohydrates, which are then used for growth and development.
Does photosynthesis and cellular respiration occur in plants and animals?
Yes, both photosynthesis and cellular respiration occur in plants and animals. Photosynthesis is the process by which plants convert sunlight into energy that the plant can use to produce carbohydrates, while cellular respiration is the process by which plants and animals convert the energy stored in carbohydrates into ATP, the main form of energy used by cells.
In plants, photosynthesis occurs within its Chloroplasts, whereas cellular respiration takes place within the plant’s mitochondria. Photosynthesis requires the use of light energy, which is converted into chemical energy, and results in the production of oxygen and sugars.
Cellular respiration then allows the plant to break down these sugars to create ATP through a series of chemical reactions.
In animals, photosynthesis does not occur, but cellular respiration does. Cellular respiration utilizes oxygen in the process of breaking down glucose, obtaining energy for the cell. The byproducts of this reaction are carbon dioxide and water, just like in plants.
What happens if a plant Cannot perform cellular respiration?
If a plant is unable to carry out cellular respiration, it will not be able to produce the energy it needs for its everyday activities. Without this energy, the plant will be unable to grow, reproduce and survive.
Without cellular respiration, the plant will also not be able to break down large molecules of organic materials such as glucose in order to release the energy stored in them. These organic molecules would instead accumulate, leading to damage to the plant.
Without energy, the plant will be unable to carry out important functions such as transporting nutrients throughout its cells, repairing damages, and synthesizing new proteins. This will result in reduced growth, and eventually death.
Cellular respiration is therefore critical for plants, as it provides them with the energy needed to carry out the activities necessary for survival.
Can plants still grow without oxygen?
No, plants cannot grow without oxygen. Oxygen is an essential element in photosynthesis, which is the process used by plants to produce the energy they need to survive and grow. Oxygen is a by-product of the process of photosynthesis and is used by the plant cells in respiration to generate energy – a process known as aerobic respiration.
Without oxygen, the plant cells are unable to produce the energy needed to continue functioning and the plant will eventually die. Although there have been experiments that have explored the possibility of photosynthesis in an anaerobic environment, the lack of oxygen for respiration means that overall, plants cannot grow without oxygen.
Can plants produce oxygen without carbon dioxide?
No, plants cannot produce oxygen without carbon dioxide, as photosynthesis requires both carbon dioxide and light energy to generate oxygen. Photosynthesis is the process by which plants use light energy to convert carbon dioxide and water into oxygen and glucose.
Photosynthesis is the primary source of oxygen and food production in the world, and many organisms depend on it to survive. Without carbon dioxide, there would be no photosynthesis, and therefore no oxygen production.
Additionally, plants take in carbon dioxide and use it in various metabolic processes such as respiration and cellular respiration, so if there were no carbon dioxide, plants would not be able to survive.
What happens to plants without carbon dioxide?
Without carbon dioxide, plants cannot survive as it is a vital element for photosynthesis. Photosynthesis is the process by which plants use energy from the sun to convert carbon dioxide and water into glucose, which plants use for food.
In order to create glucose, plants use a pigment called chlorophyll found in their leaves. Chlorophyll absorbs the energy from the sun, while the carbon dioxide and water provide the material needed to create the glucose.
Without carbon dioxide, the process of photosynthesis cannot take place and plants cannot survive. In addition, without carbon dioxide plants cannot create carbohydrates, proteins, and lipids to help store energy, which are all essential for healthy plant growth.
Without these compounds, plants will die and other organisms in the food chain could suffer or starve without a major food source.
Does cellular respiration always happen?
Yes. Cellular respiration is an essential process that takes place within cells and is driven by a series of chemical reactions which use oxygen to convert glucose into energy. The energy gained from this overall process is used by cells to carry out daily activities and sustain life.
Since cellular respiration is a necessary process for cell viability and survival, it will always happen in cells.
What is the main purpose of cellular respiration?
The main purpose of cellular respiration is to produce ATP (Adenosine triphosphate), which serves as the body’s major energy source. ATP is produced in the mitochondria when glucose is broken down to form water and carbon dioxide.
Through a series of complex biochemical reactions, energy stored in the bonds of glucose is released, and ATP is formed. This ATP can then be used to power a variety of cellular activities, including muscle contraction and the synthesis of new molecules.
Cellular respiration also generates byproducts that are necessary for cellular growth and development, such as NADH which drives a variety of biochemical pathways. Additionally, cellular respiration is an essential process for metabolism regulation and removing metabolic waste products from the body.
What happens if a plant doesn’t have oxygen?
If a plant doesn’t have access to oxygen, it will not be able to photosynthesize and will not be able to produce the glucose and oxygen that it needs to survive. Without oxygen, the plant will begin to die since it isn’t getting any energy from the process of photosynthesis.
This will limit the plant’s ability to produce growth and nutrients, which can eventually lead to its death. In addition, oxygen is necessary for the plant to respire, or to break down and use the energy it has stored in its cells.
Without oxygen, this process is heavily impeded and result in the plant having a much slower rate of growth and eventually death.
Why can there be no cellular respiration without photosynthesis?
Cellular respiration is the process of breaking down carbohydrates, like glucose, and turning them into energy. Photosynthesis is the process of using light energy from the sun and combining it with water, carbon dioxide, and other chemicals to produce carbohydrates like glucose.
Because photosynthesis produces the carbohydrates that cellular respiration breaks down, it is impossible for cellular respiration to take place without photosynthesis. Photosynthesis is the initial process that puts the carbohydrates that are needed for cellular respiration into the environment.
Without the input of carbohydrates that photosynthesis produces, there is no energy source for cellular respiration to use and thus, cellular respiration cannot take place.
In short, photosynthesis is necessary for cellular respiration as it provides the carbohydrates as the source of energy. Without the carbohydrates produced by photosynthesis, cellular respiration cannot occur.
Does cellular respiration occur simultaneously with photosynthesis in plants?
No, while photosynthesis and cellular respiration both happen within a plant, they do not occur simultaneously. Photosynthesis involves the process of taking in energy from the sun, like a plant’s version of eating, as it converts light energy into chemical energy in the form of glucose, also known as light dependent reactions.
Cellular respiration, meanwhile, is the process that releases energy by breaking down glucose molecules and turning them into ATP (adenosine triphosphate) molecules, also known as light independent reactions.
These processes require different environmental conditions and do not happen at the same time.
Photosynthesis takes place during the day, when plants can use the sun’s energy. Inside the leaves, energy from the Sun is used by the chloroplasts to convert water and carbon dioxide into glucose and oxygen.
The water is taken in through the plant’s roots and the carbon dioxide is taken in through the stomata in the leaves. During photosynthesis, light energy is broken down and stored in the form of glucose.
Cellular respiration, on the other hand, happens during the night, when the plant cannot use light from the sun. During this process, the stored glucose from photosynthesis is broken down to produce energy in the form of ATP.
This ATP is then used to power the plant’s metabolic processes like growth and repair. The oxygen that was produced during photosynthesis is used during this process, while the carbon dioxide produced is released into the atmosphere.
In conclusion, while both processes do happen in a plant, photosynthesis and cellular respiration do not occur simultaneously. Photosynthesis converts light energy into stored energy in the form of glucose, while cellular respiration breaks down that stored energy to produce ATP.
Why do plants need both oxygen and carbon dioxide to survive?
Plants need both oxygen and carbon dioxide to survive because oxygen is essential for them to carry out respiration, which is the process by which energy is released from the breakdown of glucose molecules.
Through respiration, plants produce ATP, a molecule that acts as the energy currency of a plant cell and fuels all metabolic processes. Carbon dioxide, meanwhile, is required for photosynthesis, which is the process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen.
During photosynthesis, the plant uses the carbon dioxide to combine with water molecules and use the energy from the sun to produce glucose, which it uses to fuel itself. The oxygen is then released as a by-product of this process and provides a necessary part of the air that the plant needs for respiration.
Therefore, oxygen and carbon dioxide are both mutually dependent for plants to survive and thrive.
Why do plant cells perform both photosynthesis and respiration while animal cells perform respiration only?
Plant cells perform photosynthesis and respiration because photosynthesis is the process through which plants create their energy. Photosynthesis involves using energy from the sun, carbon dioxide, and water to create energy-rich molecules like glucose.
This energy is then used to power the cell. Since plants are immobile, they depend upon the process of photosynthesis to create the energy they need to survive.
Animal cells on the other hand rely on food sources like plants or other animals to provide the energy they need. Although they can perform respiration to release energy from the food they consume, they are not able to perform photosynthesis to create their own energy.
This is because they are not able to absorb sunlight, process carbon dioxide, and produce energy-rich molecules in the same way as plants. As a result, animals rely on eating food as a source of energy.
