Under what condition do photosynthesis occur?
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. Carbon dioxide enters through tiny holes in a plant's leaves, flowers, branches, stems, and roots. Plants also require water to make their food.
Under what conditions would cellular respiration occur?
Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell.
Where photosynthesis and respiration occur in plant cells?
Photosynthesis occurs in the chloroplasts, whereas cellular respiration occurs in the mitochondria. Photosynthesis makes glucose and oxygen, which are then used as the starting products for cellular respiration.
What factors affect photosynthesis and cellular respiration?
Explanation:
- the intensity of the light being absorbed by the chloroplasts.
- the concentration and availability of CO2 (Carbon Dioxide)
- the temperature.

What are the four conditions necessary for photosynthesis?
There are four factors which are necessary for the process of photosynthesis, water, carbon dioxide, sunlight, and chlorophyll. Chlorophyll pigments are present in the plant, carbon dioxide is obtained from the atmosphere, water is absorbed from the soil by the roots.
Which conditions produce the best rate of photosynthesis?
As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis.
Why does cellular respiration occur in plants?
The process of cellular respiration allows plants to break down glucose into ATP. The ATP provides the energy they need to carry out various functions. Although plants use photosynthesis to produce glucose, they use cellular respiration to release energy from the glucose.
Where does the process of cellular respiration mostly happen?
Most of the steps of cellular respiration take place in the mitochondria. Oxygen and glucose are both reactants in the process of cellular respiration.
Where does photosynthesis occur in plants?
chloroplasts 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.
Which process is common to photosynthesis and cellular respiration?
The is answer is (e) Chemiosmosis. Both Photosynthesis and Cellular Respiration have a step in their process that generates ATP from ATP synthase. …
Does temperature affect photosynthesis?
Although the light dependent reactions of photosynthesis are not affected by changes in temperature, the light independent reactions of photosynthesis are dependent on temperature. They are reactions catalysed by enzymes. As the enzymes approach their optimum temperatures the overall rate increases.
Which of the following is needed for a photosynthetic reaction to occur within a plant?
Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.
Why sunlight is necessary for photosynthesis?
During photosynthesis, plants trap the light from the sun and utilize the energy of the light. Where this trapped light energy is used to convert to chemical energy and combine the water and carbon dioxide into glucose, which is used by the plants as their food.
Why do plants do both photosynthesis and cellular respiration?
Plants carry out both photosynthesis and cellular respiration. They make their own food, and then break down those glucose molecules later, generating ATP to power their cellular processes. Fun fact!
Where does respiration take place in plants?
As with photosynthesis, plants get oxygen from the air through the stomata. Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called "aerobic respiration".
What is photosynthesis and cellular respiration?
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
Where does cellular respiration occur?
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.
What is the optimum temperature for photosynthesis?
The optimum temperature required for photosynthesis ranges 25°-35° C.
Do photosynthesis and cellular respiration occur at the same time in a plant explain?
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.
What do cellular respiration and photosynthesis have in common quizlet?
What do cellular respiration and the light reactions of photosynthesis have in common? Both produce glucose as their final product.
Does temperature affect cellular respiration?
The increase in temperature enhances the rate of cellular respiration. It is due to the heat speeds up the reactions, means the kinetic energy is higher. It means reactions speed up and rate of cellular respiration increases.
What temperature is best for photosynthesis?
The optimum temperature range for photosynthesis is 35–40ºC.
What are the four conditions required for photosynthesis?
There are four factors which are necessary for the process of photosynthesis, water, carbon dioxide, sunlight, and chlorophyll. Chlorophyll pigments are present in the plant, carbon dioxide is obtained from the atmosphere, water is absorbed from the soil by the roots.
Which of the following is needed for a photosynthetic reaction to occur within a plant quizlet?
Plants need photosynthesis for energy and ultimately to survive. Water and carbon dioxide are reactants for photosynthesis. Chlorophyll captures sun's light energy and then plants chemically combine this with water and carbon dioxide to make glucose (sugar) and oxygen.
What is cellular respiration and photosynthesis?
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 leaves become yellow in the absence of light?
In absence of sunlight the green chlorophyll pigment gradually undergoes degradation and no new pigment molecule is formed, giving the leaves of the plant a pale yellow color.
What do photosynthesis and cellular respiration have in common?
Photosynthesis produces the oxygen to replenish oxygen that is used up by living organisms during respiration. Carbon dioxide produced during respiration is one of the reactants plants need to perform photosynthesis. Photosynthesis and cellular respiration are both part of a mutually beneficial relationship.
How does cellular respiration occur in plants?
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. This process releases carbon dioxide and water as waste products. 8. Plants have mitochondria and can perform cellular respiration.
Where does photosynthesis occur in a plant?
chloroplasts 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.
How does temperature affect photosynthesis and cellular respiration?
The increase in temperature enhances the rate of cellular respiration. It is due to the heat speeds up the reactions, means the kinetic energy is higher. It means reactions speed up and rate of cellular respiration increases. When temperature decreases, in order to conserve energy, cellular processes slow.
