Does carbon dioxide affect photosynthesis?
Temperature, carbon dioxide concentration and light intensity can affect the rate of photosynthesis. Carbon dioxide is one of the reactants in photosynthesis. If the concentration of carbon dioxide is increased, the rate of photosynthesis will therefore increase.
How does photosynthesis affect carbon dioxide?
Explanation. The rate of photosynthesis increases linearly with increasing CO2 concentration (from point A to B ). The rate falls gradually, and at a certain CO2 concentration it stays constant (from point B to C). Here a rise in CO2 levels has no effect as the other factors such as light intensity become limiting.
What does photosynthesis produce from carbon dioxide?
The process of photosynthesis is commonly written as: 6CO 2 + 6H 2 O → C 6 H 12 O 6 + 6O 2. This means that six carbon dioxide molecules and six water molecules are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules.
Why is CO2 needed for photosynthesis?
Carbon dioxide is needed for photosynthesis. The lower part of the leaf has loose-fitting cells, to allow carbon dioxide to reach the other cells in the leaf. This also allows the oxygen produced in photosynthesis to leave the leaf easily. Carbon dioxide is present in the air we breathe, at very low concentrations.
Is CO2 released during day in plants?
Plants give out carbon dioxide during respiration, which takes place during the day as well as at night. Thus, carbon dioxide is released by plants throughout the day except during photosynthesis, where it is used to make food.
During which process is CO2 released?
cellular respirationDuring cellular respiration, glucose and oxygen are changed into energy and carbon dioxide. Therefore, carbon dioxide is released into the atmosphere during the process of cellular respiration. Respiration is also the process by which once-living (organic) organisms are decomposed.
How do you prove that CO2 is released during photosynthesis?
The carbon dioxide that is released in the process is absorbed or consumed by the KOH solution that is suspended in the test tube in the conical flask, creating a vacuum or a void in the flask resulting in the upward water movement in the tube. Hence, the water level in the tube changes.
Where is CO2 released?
There are both natural and human sources of carbon dioxide emissions. Natural sources include decomposition, ocean release and respiration. Human sources come from activities like cement production, deforestation as well as the burning of fossil fuels like coal, oil and natural gas.
What is released during photosynthesis?
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. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
Which gas is released during photosynthesis?
Carbon dioxide is released during photosynthesis.
Is carbon dioxide released during burning True or false?
During burning along with energy, carbon dioxide and water vapour are also produced.
Is co2 released in glycolysis?
Carbon dioxide is not produced during glycolysis. Remember in glycolysis one glucose molecule yields 2 pyruvate, 2 ATP, and 2 NADH. Heat is also given off in form of energy as we went over before. Carbon dioxide is involved in other processes.
During which process is co2 released as a by product of oxidation reduction reactions?
Cellular RespirationCellular respiration is an oxidative process whereby an electron donor is oxidized and oxygen is reduced to produce carbon dioxide, water, and energy [3].
Which plants can photosynthesize better in lower levels of light than C3 plants?
C4 plants can photosynthesize better in lower levels of light than can C3 plants
Where do light reactions occur?
The majority of the light reactions occur on the thylakoid membranes in the chloroplast
How many kinds of chlorophyll are there?
A . There is only one kind of chlorophyll
Why are C4 plants more efficient than C3 plants?
BEcause C4 plants have special alkaloids (toxic substances), C4 plants are able to resist pest better than are C3 plants. C4 plants are more efficient CO2 fixers than C3 plants are. The change in pH over the 36-hour period could indicate that acid products were being. Produced at night.
What does the change in pH over the 36 hour period indicate?
The change in pH over the 36-hour period could indicate that acid products were being
Is the rate of photosynthesis proportional to light intensity?
The rate of photosynthesis is inversely proportional to light intensity
