Photosynthesis in plants occurs only during the day when there is the sunlight but plants respire throughout the day and night. To carry out the process of photosynthesis, sunlight is important for the plant.
Do plants carry out photosynthesis only during the day?
Plants carry out photosynthesis only during the day and respiration only at night.
Do plants photosynthesize in the day and respire at night?
For photosynthesis, the plant takes in carbon dioxide, light energy, and water to produce glucose and oxygen. Photosynthesis only happens during the daytime when there is enough sunlight. However, plants can respire at all times of the day and night, even though their stomata close at night.
Do plants respire all day and night or only during the night?
Q9) DO plants respire all day and night or only during the night? Solution: Plants respire during the night, plants release carbon dioxide and take in oxygen and oxidation of stored food by absorbed oxygen takes place. That’s why it’s mentioned that one should not sleep under a tree at night.
Do plants carry out respiration during the day?
Plants respire all the time, whether it is dark or light. However, they only photosynthesise when they are in the light. The table shows the difference between photosynthesis and respiration at different times of the day. Photosynthesis and respiration in plants during the day.
Does respiration in plants occur only at night?
The Effect of Darkness on Photosynthesis
When does respiration occur in plants? It is a common misconception that photosynthesis occurs during the day and respiration only happens at night. In fact, respiration in plants occurs all the time – both day and night, as respiration in plants is like breathing in humans.
Which plants carry out photosynthesis?
Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs.
Does photosynthesis occur at night?
During the day, photosynthesis is dominant, so there is a net release of oxygen. At night, photosynthesis stops but respiration continues, so there is a net consumption of oxygen.
Why do plants respire all day and night?
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.
Why do plants carry out photosynthesis and cellular respiration?
The main purpose of photosynthesis is to convert radiant energy from the sun into chemical energy that can be used for food. 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.
When would green plants carry out photosynthesis only during the day only at night continuously or never Why?
1 Answer. BRIAN M. The process of photosynthesis takes place continuously. The Light reaction when sunlight is available, and the dark reaction all of the time.
Why do plants make their food only during the daytime?
Answer: because solar energy is converted chemical energy or starch which is essential for the photosynthesis. green plants make there food only daytime because plants need cholorophyll to make food and cholorophyll only make with the help of sunlight.

Can carry out photosynthesis?
Plants, algae, bacteria and even some animals photosynthesize. A process essential to life, photosynthesis uses carbon dioxide, water and sunlight, and converts it into sugar, water and oxygen.
How do plants respire during night?
Plants release oxygen during the day in the presence of natural light through the process of photosynthesis. While at night, the plants uptake oxygen and release carbon dioxide, which is called respiration.
Where does photosynthesis occur at night?
In plants adapted to the arid conditions, the CAM pathway (Crassulacean acid metabolism) of carbon fixation is observed, wherein photosynthesis takes place in the daytime but the exchange of gases takes place at night. Their stomata open at night to reduce the water loss during the day through transpiration.
What happens to plants at night during photosynthesis?
When it is dark outside, the plant only consumes oxygen and releases carbon dioxide. During dim sunlight, the photosynthesis rate is the same as the respiration rate. Plants absorb the oxygen they create through photosynthesis and also uses up all the carbon dioxide it forms through respiration.
Why can’t plants photosynthesize at night?
Plants respire all the time, whether it is dark or light, because their cells need energy to stay alive. But they can only photosynthesize when they have light.
How do plants carry out photosynthesis?
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
Do all plants carry out photosynthesis?
This process is called photosynthesis and is performed by all plants, algae, and even some microorganisms. To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis.
When would green plants carry out cellular respiration only during the day only at night continuously or never?
So, the correct answer is ‘False‘.
Do plants carry out cellular respiration and photosynthesis 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.
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.
When green plants carry out photosynthesis during daytime is absorbed?
Expert-verified answer
Photosynthesis is associated with the green plants and this phenomenon happens during the day time in the presence of sunlight. The green plants absorb atmospheric carbon dioxide to produce oxygen. During nights the sunlight is absent and hence photosynthesis does not take place.
Do decomposers carry out photosynthesis?
Decomposers break down organic matter. They are sinks for plant and animal wastes, but they also recycle nutrients for photosynthesis.
Where does photosynthesis occur in plants?
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
Why photosynthesis takes place in the leaves?
Photosynthesis in numbers.
The surface of the leaf absorbs the blue and red wavelengths while the green light is absorbed deeper within the plant. This light is what’s absorbed by the chloroplasts and is most effective in photosynthesis and the conversion of energy.
During which time do green plants prepare their food?
No green plants can’t make their food at night because green plants prepares their food from the help of sunlight which is available in the morning and unavailable at night.
Do plants reverse photosynthesis at night?
During daylight hours, plants take in carbon dioxide and release oxygen through photosynthesis, and at night only about half that carbon is then released through respiration. However, plants still remain a net carbon sink, meaning they absorb more than they emit.
Do plants give carbon dioxide at night?
Carbon dioxide is not released during photosynthesis, but small amounts of that gas are emitted both day and night as a by-product of cellular respiration.
Why can only green plants produce food?
Green plants are the only ones who can make their own food because their appearance of green is due to a pigment known as Chlorophyll…… This Chlorophyll is also responsible in making their own food by the process of Photosynthesis, which requires Sunlight along with Chlorophyll…..
Why do plants make their own food Class 2?
Plants are primary producers, they synthesize their own food. These autotrophs, use photosynthesis to transform sunlight, water and compounds such as oxygen and carbon dioxide into simple food – sugars. It is their fuel.
How do plants without chlorophyll photosynthesis?
A plant with no chlorophyll means there is a plant that does not produce its own food via photosynthesis. Actually, there are approximately 3000 non-photosynthetic plants around the world! Rather than producing their own food, they can parasitize other plants or fungi.
Do plants only use cellular respiration?
While both plants and animals carry out cellular respiration, only plants conduct photosynthesis to make their own food.
