When it becomes dark, a plant continues to undergo cellular respiration to convert stored glucose into energy (ATP) for its metabolic processes. Unlike photosynthesis, which requires light, cellular respiration occurs continuously, utilizing oxygen to break down glucose. The byproducts of this process are carbon dioxide and water, which the plant can later use during photosynthesis when light is available again. Thus, even in darkness, plants rely on cellular respiration to meet their energy needs.
What else can I help you with?
Where do the reactants come from and what happens to the products after they are made of cellular respiration?
The reactants for cellular respiration, glucose and oxygen, come from the food we eat and the air we breathe. Once products like ATP, carbon dioxide, and water are produced, they are used as energy sources for various cellular processes or expelled from the body through exhalation.
Is the energy involved in photosynthesis and cellular respiration recycled?
Solar energy is transformed into other types of energy once it is in the biological cycle. The only way it may be released is as heat energy into space. Sunlight powers photosynthesis, and the ultimate function of this stored chemical energy is as mechanical energy and waste heat.The energy that plants store may be used in cellular respiration, but never goes back to the plant. The physical materials are mostly recycled (water, carbon dioxide, and trace nutrients) because cellular respiration undoes the chemical changes of photosynthesis.
How might an organism benefit by carrying Out fermentation instead of cellular respiration?
Organisms prefer cellular respiration over fermentation.Cellular respiration gains a cell 38ATP molecules per every glucose molecule.Fermentation only gains 2ATP per glucose molecule.Obviously, you can see the difference. Cellular respiration provides much more energy for the cell, and this is why they prefer this over fermentation.There are organisms like facultative anaerobes that can preform either process, but they do cellular respiration if oxygen is available. These organisms only preform fermentation if they are in an "oxygen debt." (Like when you run, you are using a lot of energy, and you cannot get enough oxygen for cellular respiration. You are in "oxygen debt," and your muscle cells start doing fermentation. But your muscle cells prefer using aerobic reparation (cellular respiration) so you start panting. Once you get your breath back, oxygen is restored and your cells again preform cellular respiration and get more energy faster.)However, there are still obligate anaerobes that are poisoned by oxygen, and only use fermentation.Hope this helped!!
What happens to the glucose and oxygen once there made in photosynthesis?
During photosynthesis glucose and oxygen are made by the plant. The glucose made is used by the plant as a form of food and the oxygen is discarded as a waste product.
Where do the new carbon-containing molecules (glucose) go once they've been made in a plant?
Once glucose is produced in a plant during photosynthesis, it is primarily used for energy through cellular respiration, fueling growth and metabolic processes. Additionally, glucose can be converted into starch for long-term energy storage and stored in various plant tissues. Some glucose is also used to synthesize other organic molecules, such as cellulose for cell walls and various fats and proteins, contributing to the overall structure and function of the plant.
Is it true that plants do not undergo cellular respiration?
No, this is not true, all organisms undergo cellular respiration. Only the green (chlorophyll containing) cells of a plant can perform photosynthesis to build sugars using the energy from sunlight, these cells and other cells in the plant (that can't perform photosynthesis) break down those sugars through respiration to get the energy they need (in the form of ATP) to perform other cellular functions. All photosynthesis is, is a way to capture the energy of the sun, once that energy is captured, the plant releases and uses that energy the same way as any other organism. Cellular Respiration.

What modifications of cellular respiration might you expect to find in dormant seeds?
In dormant seeds, cellular respiration is typically reduced to minimal levels due to limited oxygen availability and low metabolic activity. The seeds rely predominantly on anaerobic metabolism for energy production. Once the seeds germinate and become active, cellular respiration increases to support growth and metabolic processes.
How does photosynthesis and cellular respiration form a cycle?
The two chemical reactions essentially form a cycle, in that the products of one reaction fuel the other. CO2 and H2O released from cellular respiration reenter the atmosphere and are recycled by photosynthetic organisms, which in turn produce the sugars and oxygen needed for respiration to occur once more.

How do herbivores get glucose for cellular respiration?
Herbivores obtain glucose for cellular respiration by breaking down carbohydrates found in plants through digestion. Once ingested, these carbohydrates are broken down into glucose molecules, which can then be used as a source of energy by the herbivore's cells.
What is the use of insulin in the cellular respiration?
Insulin helps regulate blood glucose levels by promoting the uptake of glucose into cells. Once inside the cells, glucose can be used in cellular respiration to produce energy in the form of ATP. Insulin also helps in the storage of excess glucose as glycogen in the liver and muscle cells.
How does oxygen cross into the cell to support cellular respiration?
Oxygen crosses into the cell through a process called diffusion. It moves from areas of high concentration outside the cell to areas of low concentration inside the cell. Once inside, oxygen is used in the mitochondria to support cellular respiration, where it helps produce energy for the cell.
What happens to the glucose and oxygen once there made in photosynthesis?
During photosynthesis glucose and oxygen are made by the plant. The glucose made is used by the plant as a form of food and the oxygen is discarded as a waste product.

Do cellular respiration and fermentation have any similar reactions?
Both start with glycolysis... but once you reach pyruvic acid, they're very different. Respiration final product is an inorganic compound (oxygen) whereas fermentation final product is an organic compound (such as lactic acid or ethanol)
